Audio Issue on a Sansung 300E4A-BD2 with Slackare 14.0

Evariste_Galois · 12-29-2012, 10:22 AM

Recently I installed Slackware 14.0 in a Sansung 300E4A-BD2 (with double boot), and I'm facing some trouble concerning the audio. Internet videos are playing without audio; VLC point error in the "default" device, while Mplayer is running without problem. XMMS and Amarok do not play audio files, pointing a possible error in the drivers. My lspci, lsmod | grep snd and cat /proc/asound/card*/codec#* | grep outputs are, respectively

What is the contents of /proc/asound/cards ?

Device 0 will normally be the default output device. For some applications you can reroute that by adding one line in ~/.asoundrc

defaults.pcm.card 1

Where 1 is the not 0 card that you would rather use by default. If you're using pulseaudio, you can change the default card with pavucontrol. Assuming everything is installed and configured in a usable way. It's a good idea to re-index your cards so the card that you want to be your default is 0. It only takes a few lines /etc/modprobe.d/<some_file.conf>.

alias char-major-116 snd
alias char-major-14 soundcore
options snd-ice1712 index=0

In my case. Probably snd-hda-intel in your case.

The contends of /proc/asound/cards are:

Code:

0 [Generic       ]: HDA-Intel - HD-Audio Generic
                    HD-Audio Generic at 0xfeb44000 irq 42
1 [Generic_1     ]: HDA-Intel - HD-Audio Generic
                    HD-Audio Generic at 0xfeb40000 irq 46

I created an snd-hda-intel.conf in the /etc/modprobe.d/ folder, but it didn't work. Thanks in advance.

I guess I shouldn't be surprised. It is likely that the motherboard and the video card has the same audio chipset. But which is which and how to index them specifically. And you thought that halloween had already passed.

http://www.alsa-project.org/main/ind...dule-hda-intel

$ modinfo snd-hda-intel

the ones prefixed with "parm:" are the ones you can set on the options like. It looks like id= might be of use.

$ cat /proc/asound/card0/id

and for the other cards as well, and add the id=<results_form_proc> to the options line to single out the device.

In my case...

options snd-ice1712 id=M44 index=0

hopefully they both don't have the same id value. lspci might help further identify / isolate which is the real slim shady. You can reference them with hw:0 or hw:1 as a last resort. "-ao alsa:device=hw,1" for the mplayer syntax.

@Shadow_7, I'm sorry, but I got quite confused about what I have to do; could write more details; thanks in advance.
