problem with sound configuration

igb · 10-23-2010, 05:19 PM

I am using slackware-current on my new asus 1215n and i have a silly problem. The sound works when you plug-in a headphone but with speakers i have no sound. I checked it in Win7 and there is no hardware problem and i dont know what to do atm.
Here is the audio device info given by 'lspci -v'

I would suggest running "alsamixer" and making sure the speaker channels are not muted. (Press left and right arrow keys to select different channels, and the "M" key to mute or unmute)

speakers channels are not muted. Here is the output of amixer

Perhaps make sure that the program you are using to test the sound does not have "Headphones" selected as output? Or try another program to test it with, maybe it's just the one program you have trouble with.

I tried with smplayer, audacios and mpg123 they all do the same thing. Voice is ok with headphone jack but no voice in speakers.

I don't know what it could be, sorry. The only other thing I could recommend is downloading and updating ALSA from their website here. I know in the past when I had sound problems, that fixed it for me.

According to this http://forums.gentoo.org/viewtopic-t...c-start-0.html you need to supply a model option to the snd-hda-intel kernel module.
Create a file snd-hda-intel.conf in /etc/modprobe.d/ that contains the line:
