 Posted: Tue Apr 06, 2021 4:46 am Post subject: No Sound - aplay Cannot Open Any Device |
 |
|
I recently made my way through a Gentoo install for a home built machine and have just about everything working except sound. The motherboard is micro ATX and so has the standard 3 rear port arrangement, along with a front mic and headphone port. The graphics card is a Radeon RX 550 with HDMI and DP. There is also a native motherboard HDMI, but the processor has no integrated graphics so that one is inactive. I know this question gets asked a lot over the years, but it looks like the causes are varied.

The only thing weird about the last one is the "No soundcards found" message, but it looks like everything is there.
So here are some failed command outputs:
| Code: | ~ $ aplay track01.cdda.wav

Using sudo does not help this. Interestigly, alsamixer seems to be OK. As card0 is the default, alsamixer and alsamixer -c 0 are the same:

I know they are muted, but that should not cause an error. What can I do to investigate the cause of this? |

PoissonAerohead,
That all looks "mostly harmless" except for the
| Code: | Card: HD-Audio Generic
Chip: Realtek Generic |
in alsomixer.
Please put your entire dmesg and kernel .config onto pastebins.
Logs are useful for what they show and for what they don't show that should be there but is missing.
We can't deduce the missing stuff from filtered logs.
wegetpaste can help with pastebins.
Which sound output do you want to use?
One of the outputs on the video card, or the on board analogue output?

If you have already created the ~/.asoundrc configuration file (remember to delete it if you will install pulseaudio), you can try to add your user to the audio group:
| Code: | | sudo usermod -a -G audio <your username> |
Or you can try changing the output to another card...

gasmat: my user is already in group audio, but I tested with sudo as well anyway.

Please see the following links:
dmesg: https://dpaste.com/3WE36JZZ3
kernel config: https://dpaste.com/ANDCXN58B
Please let me know if there is anything else I can post or try.

As I am getting the computer up and running, ideally I would like to prove both outputs work. I can then select what I want in an asoundrc. There are positives to each. HDMI allows for loudness control with the TV remote. Apparently, though, only one program can use it at a time, unless you put a particular setting in asoundrc which will cause some quality degradation? Also, apparently the beginning of the audio is chopped up as the connection is made? I need to get it working to verify how big these issues these are. Using rear port analog sound is not as slick as HDMI, but may avoid these issues and I can always put an ordinary sound bar under the TV (I was attempting to test the rear sound port last night with basically a very cheap item like this). Any advice regarding this is welcome. |

PoissonAerohead,
Until you know which codec you need build all the codecs.
| Code: | CONFIG_SND_HDA=y
CONFIG_SND_HDA_INTEL=y
# CONFIG_SND_HDA_INTEL_DETECT_DMIC is not set
CONFIG_SND_HDA_HWDEP=y
CONFIG_SND_HDA_RECONFIG=y
# CONFIG_SND_HDA_INPUT_BEEP is not set
CONFIG_SND_HDA_PATCH_LOADER=y
# CONFIG_SND_HDA_CODEC_REALTEK is not set
# CONFIG_SND_HDA_CODEC_ANALOG is not set
# CONFIG_SND_HDA_CODEC_SIGMATEL is not set
# CONFIG_SND_HDA_CODEC_VIA is not set
CONFIG_SND_HDA_CODEC_HDMI=y
# CONFIG_SND_HDA_CODEC_CIRRUS is not set
# CONFIG_SND_HDA_CODEC_CONEXANT is not set
# CONFIG_SND_HDA_CODEC_CA0110 is not set
# CONFIG_SND_HDA_CODEC_CA0132 is not set
# CONFIG_SND_HDA_CODEC_CMEDIA is not set
# CONFIG_SND_HDA_CODEC_SI3054 is not set
CONFIG_SND_HDA_GENERIC=y
CONFIG_SND_HDA_POWER_SAVE_DEFAULT=0 |
| Code: | | CONFIG_SND_HDA_CODEC_HDMI=y |
will be right for the HDMI outputs.
The loosing the first few seconds on HDMI output, while the stream is opened is a real thing.
The 5.10 kernel has a hack which is equivalent to playing silence, which you da as follows.
Create a file /etc/local.d/play_silence.start with the following content.
| Code: | #!/bin/bash
# due to a kernel bug, alsa takes a few seconds to open a
# stream to HDMI (all digital?) outputs, so the first
# few seconds of everything are lost.
# the work around is to continuosly play silence
# so that the sound stream is never closed.
aplay -c2 -r48000 -fS16_LE < /dev/zero & |
You will get dmix for free.
Rebuild your kernel and boot into the new kernel. Use to check the build time is newer than Mon Apr 5 17:54:33 PDT 2021 as that's the build time of the kernel that was running when you posted dmesg.
None of this stops HDMI working but you will probably need an /etc/asound.conf to route output to the right device.
As you say, all the HDMI outputs on your video card are muted.

Card 1 (Generic Analog) is still giving me the error. I figured out how to not get an error on Card 0, and I think it may just be getting the syntax right. There is still no sound:

Playing WAVE 'track01.cdda.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
^CAborted by signal Interrupt... |
While playing to the hdmi device I went into alsamixer -c 0 and attempted to unmute each item individually (S/PDIF [0-4]?) and then all items simultaneously. I turned up the television volume and there was no sound. Note that I can to toggle between MM and 00 with the m key, but when it is unmuted, I cannot change the level. Is this normal for HDMI? 0 is no gain reduction anyway...
EDIT: I just plugged the TV into my newer laptop, which has an HDMI port. It is running Parabola, which is an Arch derivative. There is only 1 card, which has both the analog speaker and the HDMI outputs. The same thing happened (I muted the speaker and headphones and tried toggling all the S/PDIF items and no sound played on the TV). I am thinking there is something I do not understand about how to get sound to HDMI. |

PoissonAerohead,
Lets stick with HDMI as that's nearly there. Analogue is looking better too.
Here you have 5 HDMI outputs, they are devices 3, 7, 8, 9, and 10 on card 0.
I've removed card 1 for clarity.
| Code: | ~ $ cat /proc/asound/devices
1: : sequencer
2: [ 0- 3]: digital audio playback
3: [ 0- 7]: digital audio playback
8: [ 0- 8]: digital audio playback
9: [ 0- 9]: digital audio playback
10: [ 0-10]: digital audio playback
11: [ 0- 0]: hardware dependent
13: [ 0] : control
33: : timer |
Unless you tell alsa differently, it sends output to cand0 devece0, which is not what you want. You need to send the output to one of the devices you have got. That's 3, 7, 8, 9, or 10
Its trial and error which one.
Make an /etc/asound.conf
| Code: | pcm_slave.slave_rate48000Hz {
# 2: [ 1- 3]: digital audio playback
# 3: [ 1- 7]: digital audio playback
# 4: [ 1- 8]: digital audio playback Video Card DP
# 5: [ 1- 9]: digital audio playback
# 6: [ 1-10]: digital audio playback
pcm "hw:1,8"
# This is the rate the sound card does.
# Any random input rates are resampled to this.
rate 48000
}
pcm.rate44100Hz {
type plug
slave slave_rate48000Hz
}
defaults.pcm.card 1
defaults.pcm.device 8
defaults.ctl.card 1 |
This provides sample rate conversion to 48000 samples/sec, which is what HDMI sinks expect.
The comments reflect my system. You will need changes in 4 lines.
| Code: | defaults.pcm.card 1
defaults.pcm.device 8
defaults.ctl.card 1 |
You need card 0 in two places there, where I have card 1.
The is hw:<card>,<device> so you want card 0
The 8 in defaults.pcm.device 8 and in pcm "hw:1,8" is the device on the card that alsa will send output to.
You may not have 5 physical HDMI outputs on your video card but the electronics are there.
The /etc/asound.conf is read every time you play something, so there is no need to reboot to test.
Its correct that there are no volume controls on any digital outputs. A digital output is up to eight multiplexed channels. Volume contol would require demultiplexing, some digital multipliers then remultiplexing. That can't be done without changing the latency. Its both difficult and expensive, so its not implemented. Its much simpler once the audio has been converted back to the analogue domain. In short, use the controls on the sound system that is rendering the digital signal.

Thanks, I found it (HDMI 9). Its weird that the card registers all 5 HDMI ports even though only the fourth exists. I should think the information is available through the gpu driver in some way too.

OK I thought so, makes perfect sense. Multiplication in the analog realm is basically at the speed of light in a semiconductor of a few millimeters, in the digital domain it is at least 100 clock cycles (plus decode and re-encode).
I saw in an old posting of this question that someone watched aplay in strace or some program like that to find out the incorrect path, so I will research that and see if I can determine what is wrong (or at least pose a more useful question to you). |

PoissonAerohead,
All five are in the HDMI electronics on the video card. You just have one physical connector.
When the masks are made to manufucture the chip, its step and repeat. Which is trivial.
Its allows the same chip to be used on video card with up to 5 outputs, rather than needing different chips or several chips.
The software can see all the electronics, even if its not all utilised.
Getting back to analogue
| Code: | Card: HD-Audio Generic
Chip: Realtek ALC891 |
That HD-Audio Generic makes me nervous. I'll poke about your pastebins some more.
Don't lose your working for HDMI /etc/asound.conf because the approach is going to be make one work, then the other, which will break the first.

Thanks, please let me know if there is any further information I can provide. You are right that it seems weird the card has no name when the chip clearly does now. Is there maybe somewhere I can get a vendor name/number? In a verbose version of lspci or directly from /sys or /proc? Maybe I canl try some installation media (Gentoo or Arch maybe) that have enormous kernels and see if I can get more info, and if so, check lsmod or something?
I'm not sure if this would be relevant, but I was thinking of maybe unplugging the HD Audio plug on the motherboard that goes to the font (there is a front headphone jack and mic input) to see if that cuts down on my options at all. Additionally, I do intend on running it in some kind of tracer or debugger to see exactly what it is trying to open, since the aplay message is a bit terse and uninformative.
I understand the manufacturing reason for the hardware to be the same across many devices. I'm just surprised that the card actually reports all 5. I would have expected the firmware on the card to just ignore the other 4, but I guess that is not how it works. Also, to be clear, the video card has 1 HDMI, 1 DP, and one DVI. I believe the DP also carries sound and i do not see a DP in the aplay output or in alsamixer. Does ALSA view this as the same as HDMI?
Yes, I'll be sure not to lose the working config I have for now. |

PoissonAerohead,
Sorry, I dropped this thread. Yes, HDMI and DP both carry digital audio. That's two of your HDMI sound outputs.
Alsamixer cannot determine the physical connector. You can do the same trial and error with the display port if you like.
Getting back to analogue audio, there is no need to unplug anything. Be aware that alsa may mix up some of the control naming, so that Headphone and something else is swapped over.
It will do that regardless of what actually connected.
Lets recap with a self consistent data set. That will be so we can see the hardware. It has the Vendor and device IDs.
The full dmesg, so we can see what the kernel did as it detected your hardware.
The full kernel .config, in case we need to change it.
The last two items need to go onto a pastebin.
Something to check in the BIOS. Many system allow you to choose between AC97 and High Definition for the front panel connector.
AC97 is an old standard that has a different pin out to High Definition. If you have that option at all, choose High Definition.

For what it's worth, the motherboard is small and so fits the 6 usual audio ports into 3 (blue, green, and pink only) https://biostar-usa.com/app/en-us/mb/introduction.php?S_ID=881. I'm not sure if this requires any special configuration (because the 6 usual ports actually clash with one another).
Additionally, this Vendor/Product combination (1565:824d) has turned up at this fedora forum, with a nice list of working platforms (Gentoo is not mentioned as it is not for the faint of heart). This gives me confidence that at least Arch and a few others can work with it. I may do a little Installer investigation like I described to see if I learn anything useful. I don't think their modprobe suggestions will help me, as I have everything built in. https://ask.fedoraproject.org/t/audio-output-problem-in-fedora-31/4456 |

The numbers that matter are the Vendor and Device IDs at the end of the first line of output for each device.
dmesg looks OK too. | Code: | [ 1.374485] #0: HDA ATI HDMI at 0xfce60000 irq 61
[ 1.375351] #1: HD-Audio Generic at 0xfc900000 irq 63 |
Just the generic does not sit well.
We know that you only need | Code: | CONFIG_SND_HDA_CODEC_REALTEK=y
CONFIG_SND_HDA_CODEC_HDMI=y |
for codecs. The others are just bloat.

As you have lots of analogue sound inputs and outputs multiplexed into three jack sockets, the hardware may not auto detect the right multiplexer setting.
To fix that it needs module parameters passed to snd_hda_intel when it starts. See /usr/src/linux/Documentation/sound/hd-audio/models.rst for a list of model= parameters.
Eww. Your codec isn't listed.
The general idea in that you do trial and error with the model= list for your codec until you find one that works.
The hard way to do this is with sound support built into the kernel. Module parameters are passed on the kernel command line. See the top of /usr/src/linux/Documentation/admin-guide/kernel-parameters.rst
All those reboots get tiring. It may be faster to rebuild the kernel with snd_hda_intel and the codecs made as loadable modules so you can use | Code: | modprobe -r snd_hda_intel
modprobe snd_hda_intel model=<next_on_list> |
to find one that work.
You need a model list, or maybe one of the other ALC ones work.
It gets a little more complex too. The analogue sound card is card1, so you need an /etc/asound.conf to redirect output to card1.
If you have never tested with a suitable /etc/asound.conf, maybe it just works :)
