buddy24 · 01-17-2010, 12:32 AM

Hi, I'm new to Linux and recently installed mepis 8.0. on my sony vaio, VGN-N130G...

before installing as my sole OS, I did check that sound and video are working fine. But after installation, after reboot, sound is not coming. No sound for MP3, VCD or youtube... all were working fine earlier... Not sure wht went wrong and when?

Is it a problem of sound drivers...

this is output lspci :

For your card, this is the audio driver you should have installed.

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

To find out it it is loaded, open a konsole and run the command '/sbin/lsmod | grep snd' ( without the quotes ).

If it is loaded, you will get a listing like this:

Quote:

/sbin/lsmod | grep snd
snd_hda_codec_realtek 295412 1
snd_hda_intel 31240 2
snd_hda_codec 90608 2 snd_hda_codec_realtek,snd_hda_intel

snd_timer 26720 2 snd_seq,snd_pcm

soundcore 9920 2 snd
snd_page_alloc 11072 2 snd_hda_intel,snd_pcm

If you get nothing, then it is not loaded. If it is loaded, then in a konsole try the command

'aplay somewavefile.wav' ( that is any wav file ). If you get sound, then you are missing codecs to decode mp3's, etc.

Post back your results.
