Need help in sound configuration[SOLVED]

Hello,

Under Gnome 3, in the “Sound” dialog, under “Hardware* tab I have three items listed: Digital Stereo (HDMI) output, webcam and Internal Audio output. When chatting, the sound under HDMI is horrible, but under Internal Audio the output is excellent. But even if I select the Internal Audio, it doesn't persist, after closing the dialog the default jumps back to HDMI.

My question is, how can I make Internal Audio as my default output?

Is it any way to disable completely HDMI because it just gives me trouble.

Thank you,
Jmak

Assuming you're using ALSA you should be able to force different sound card using a ".asoundrc" file in your home directory which overrides the default ALSA settings per user.

https://wiki.archlinux.org/index.php/Ad … User_Space

Mine simply looks like this:

defaults.ctl.card 1
defaults.pcm.card 1
defaults.pcm.device 0

Which sets ALSA to my USB audio device instead of the build in sound card

Re: Need help in sound configuration[SOLVED]

Thanks,

It didn't help.

When testing alsa, I get this error message:

[mak@(none) ~]$ aplay /usr/share/sounds/alsa/Front_Center.wav

What is the output of "aplay -L"?

Channels count non available

Your "ctl" (short for "control") entry is probably wrong, as a guess.

Re: Need help in sound configuration[SOLVED]

Maybe this is clue for someone understands about sounds.

I found by accident that if I play:

[root@(none) mak]# aplay /usr/share/sounds/alsa/Front_Center.wav

it works fine.

But as user:

[mak@(none) ~]$ aplay /usr/share/sounds/alsa/Front_Center.wav

it doesn't work.

As a sanity check, what is the output of groups, when run as you normal user?

Re: Need help in sound configuration[SOLVED]

OK. Solved.

This happens when you don't understand what you are doing.

Me silly, I just copied and pasted the parameters “kwakshot” gave without changing the card numbers relevant to mine.

Now that I modified like this:

defaults.ctl.card 0
defaults.pcm.card 0
defaults.pcm.device 0

Everything works fine.

Thank you very much for helping.
