Dell Precision: Sound problems

alfredo10 · 06-18-2011, 04:43 AM

Hi!
In PCLinuxOS (Gnome + KDE) and Mint (Katya + LMDE) I have sound problems: No sound / noises. After having added

Code:

options snd-hda-intel model=auto

to the file alsa.conf or similar
and adjusting channels with

Code:

alsamixer

sound works, but after reboot I have to repeat the procedure.
Is there a possibility to make the modifications /alsamixer
persistent?

Code:

aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: STAC92xx Analog [STAC92xx Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
cat /proc/asound/card0/codec#* | grep Codec
Codec: IDT 92HD71B7X

After you adjust your sound levels with alsamixer (and thing work!) do (as root)

Code:

alsactl store

That ought to do it.

Hope this helps some.

Do you by any chance have alsaconf available on your system (probably in /usr/sbin)?

If so, actually log in as root and execute

Code:

alsaconf

(It examines your hardware and writes the configuration files for you.)

Then, still logged in as root, execute

Code:

alsamixer

and set your levels and all that; then try playing an MP3 file with, say, mplayer. Make sure that "OO" appears at the bottom of the sliders (the space bar switches between "MM" and "OO").

If that works, still logged in as root, simply execute

Code:

alsactl store

to save the settings.

Exit, log in as somebody else and try playing an MP3 file with, say, mplayer (you may need to reboot but that's unlikely).

If you're using KDE, make sure the volume control (it's on the panel) is muted and that the level is roughly half or better (don't know where any of that is in GNOME).

I have the same hardware you do -- the above works just fine.

Hope this helps some.
