 |
|
I have not been playing music very often on my fitlet2 home desktop machine, but in the past it worked. My system is completely updated and works fine. However, today I did some CD ripping and mp3 comversion, so when I tryed to play az audio file there was no sound. Some relevant xterm command outputs: | Code: | janos@andraslinux ~ $ lspci | grep -i audio
00:0e.0 Audio device: Intel Corporation Celeron N3350/Pentium N4200/Atom E3900 Series Audio Cluster (rev 0b)
janos@andraslinux ~ $ aplay -L
null

...

janos@andraslinux ~ $ cat /sys/class/sound/card*/id

janos@andraslinux ~ $ speaker-test -t wav -c 2
speaker-test 1.2.9
Playback device is default
Stream parameters are 48000Hz, S16_LE, 2 channels
WAV file(s)
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 64 to 1048576
Period size range from 32 to 524288
Using max buffer size 1048576
Periods = 4
was set period_size = 262144
was set buffer_size = 1048576
0 - Front Left
1 - Front Right
Time per period = 2.685985
...
janos@andraslinux ~ $ |
and it keeps going 0 - 1.. without any sound. I ran out of troubleshooting ideas. Can anyone please help?
Could it be that my fitlet2 sound output hardware became defective?

I do not have pulseaudio installed, I have alsa as slected: | Quote: | media-libs/alsa-lib-1.2.9
media-libs/alsa-oss-1.1.8
media-libs/alsa-topology-conf-1.2.5.1
media-libs/alsa-ucm-conf-1.2.9
media-sound/alsa-utils-1.2.9
|
One thing I noticed that when I turn on or off the computer I do hear a click in the speakers, therefore the computer hardware (audio out) is probably not defective.
I did folllow (checked again) the gentoo alas instructions. Do I need pulseaudio on top of alsa?

| PulseAudio is only required if you have usage requirements that cannot be met by simple ALSA. More importantly for this thread, PulseAudio cannot work unless ALSA works, so if ALSA is currently broken for you, PulseAudio will also be silent. |

Understood.
Strange thing: is alsa running? | Code: | janos@andraslinux ~ $ rc-status

janos@andraslinux ~ $ su -c "rc-service alsasound stop"
Password:

janos@andraslinux ~ $ |
Alsa does not show in services at current run level. Should I add it to "default" run level? |

jankom,
What does show for your audio devices?
What is the content of /proc/asound/devices?
It looks like you have several audio devices.
Which one do you want to use?
The alsasound service saves and restores alsa settings across boots.
If its not started you sound will be muted at boot time.

jankom,
Your chipset requires SND_SOC_INTEL_SKYLAKE together with the SND_SOC_codecs and the sys-firmware/sof-firmware package to provide the firmware.
You did not post the content of /proc/asound/devices.
I suspect that its almost empty.

The funny thing that sound worked fine a few months ago, and all I did was occasional eix-sync and some network related stuff.
Yes, I did compile the most recent kernel but did not change kerenel configuration.

I guess the Headphone is where I plug in my external speakers. I do not have internal speakers in the tiny fitlet2 box. So apparently the Headphone is not working.

| Start up alsamixer, select the device with F6 and crank up + unmute everything. Sometimes the names of the outputs are just inaccurate. |

I see in your .asoundrc mixed "spdif" (digital output) and "card 0 device 0" (analog output), IMHO it is wrong.
Try rename this config (to .asoundrc.bak for example) and run "sudo /etc/init.d/alsasound restart"

Thank you all for offering ideas. Here is the latest (and this also corrects one of my earlier "code" posting): | Code: | janos@andraslinux ~ $ su -c "/etc/init.d/alsasound restart"
Password:
* WARNING: you are stopping a boot service

janos@andraslinux ~ $ amixer sset Master unmute

Mono:
Front Left: Playback 83 [95%] [-3.00dB] [on]
Front Right: Playback 83 [95%] [-3.00dB] [on]
janos@andraslinux ~ $ amixer sset Headphone unmute
amixer: Unable to find simple control 'Headphone',0
janos@andraslinux ~ $ amixer sset Speaker unmute

Still no sound, no assound or .assound file after restartting alsasound daemon

jankom,
| Code: | janos@andraslinux ~ $ cat /proc/asound/devices
2: [ 0- 0]: digital audio playback |
That's you front stereo analogue output the [ 0- 0] means card 0 device 0, which is what alsa will use by default.
There is no remapping.or anything required, so no /etc/asound.conf or ~/asoundrc.
Hide those files if you have them.
Open alsamixer and mute everything.
Unmute only Front, Mastar, Headphones and PCM then set the sliders to 70%
snd_hda_intel can operate at the 48kHz or 44.1kHz sample rates but only one at a time.
If any digital outputs are enabled only digital outputs work.
Digital controls have IEC or S/PDIF in their names. Hence mute everything, then only unmutes what yo may need.

SOLVED!
That was it. So simple yet frustrating. S/PDIF controls were not muted in alsamixer.
Back to listening to good music on my favorite linux computer.
Lessons learned:
* There is no ~/.asoundrc or /etc/asasound.conf file, sound works fine without it.
* "speaker-test -c 2" command works and you can hear which side is Right or Left.
* alsa daemon "/etc/init.d/alsasound" starts at boot level and it is running, but rc-status command (current, default run level) does not show it.
Thanks again,
