Good day, experts!
I'm trying gentoo after some years again. I got almost everything working perfectly. But this time I can't get the sound to work. Kmix doesn't detect it (I use KDE), Firefox doesn't have sound either. But with VLC I can choose the output and the sound works there.

cesarguere,
You have two PCI sound cards
| Code: | 05:00.1 Audio device: NVIDIA Corporation TU116 High Definition Audio Controller (rev a1)
07:00.4 Audio device: Advanced Micro Devices, Inc. [AMD] Starship/Matisse HD Audio Controller |
Card 0 will be your Video card HDMI outputs,
Card 1 is your analogue audio.
We need to know which card you would like to be the default and we need to see the content of /proc/asound/devices to help you write an /etc/asound.conf file.
Right now, alsa is trying to use card 0 device 0, which may not even be connected.

thaks for answering!
/proc/asound/devices
| Code: | 2: [ 0- 3]: digital audio playback
3: [ 0- 7]: digital audio playback
4: [ 0- 8]: digital audio playback
5: [ 0- 9]: digital audio playback
6: [ 0- 0]: hardware dependent
7: [ 0] : control
8: [ 1- 0]: digital audio playback
9: [ 1- 0]: digital audio capture
10: [ 1- 2]: digital audio capture
11: [ 1- 0]: hardware dependent
12: [ 1] : control
33: : timer
|
/etc/asound.conf : not exist!
I actually use both outputs. The HDMI (I have my PC connected to the TV and use its speakers) and the analog one I use to connect headphones. But first I would like to know how to use the HDMI output. |

cesarguere,
From /proc/asound/devices we can tell that the nVideo card is card 0 as it has no capture (input) devices.
| Code: | 2: [ 0- 3]: digital audio playback
3: [ 0- 7]: digital audio playback
4: [ 0- 8]: digital audio playback
5: [ 0- 9]: digital audio playback
6: [ 0- 0]: hardware dependent
7: [ 0] : control |
The first number, before the colon (:) is the device minor number.
The numbers in the brackets [ 0- 3] are the card and the device that we need for /etc/asound.conf.
The will be some trial and error here.
Create a file /etc/asound.conf that contains (my example)
| Code: | defaults.pcm.card 0 # Video HDMI
defaults.pcm.device 10 # Display output |
Your defaults.pcm.device number will be 3, 7, 8 or 9. They may not all exist as physical connectors on your video card.
Fix the permissions and ownership to be | Code: | | -rw-r--r-- 1 root root 1850 Jul 29 2023 /etc/asound.conf |
Now the good news /etc/asound.conf is read every time an application needs it. No reboot or service restarts required.
Just restart your media player.

Thanks for answering!
It's really weird what happens on my system. After trying to change /etc/asound.conf Firefox still has no sound (I tried all the variations -pcm.card 0 to 1 and pcm.device 0 to 10-)
konqueror has only analog sound (even if I delete /etc/asound.conf)
google-chrome has only analog sound (even if I delete /etc/asound.conf)
vlc starts on default device without sound but it has an option to change the output device. In vlc changing the device, I can choose between the options and I can hear sound from the tv's hdmi and I can change to the analog output too and it works perfectly.
kmix never recognizes the sound. System notifications have no sound.
with alsamixer I can modify the sound volume of konqueror and chrome. but if I change to nvidia hda card I see 4 s/pdif outputs that I can't modify and no sound in the system.
It seems to me that creating and modifying the /etc/asound.conf file produced no changes. |

cesarguere,
Digital outputs do not have volume controls, only [MM] mute switches.
