I'm running Mandriva 2006 on an acer aspire 1640 laptop and have no sound.
lspci gives
00:1b.0 Class 0403: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition Audio Controller (rev 04)

But the specs say it's got a realtek audio driver.

lsmod gives

any help would be greatly appreciated as I've tried loads of 'solutions' and am still without sound
Thanx

have you tried any live distros like knoppix to see if they manage to get the sound working or have you just tried with mandriva?

tried Ubuntu dapper (beta) and got sound but no video!
I'll get back to you with a list of live cds and whether I get sound or not.
Thanx

so far I've got sound from Backtrack but none from Auditor or Anonym.os
I'll try some more later and get back to you
Thanx for your help

So there appears to be some kind of configuration error...did you try the administrative tools that come with mandriva...cant remember what they are called.

oh yeah .... went through the whole mcc thing and the troubleshooting procedure. Still no luck. I've tried alsa-utils, still no luck. And I've downloaded the latest linux drivers from the realtek site. Still nothing. ALSA has the snd-hda-intel driver selected. Do you know if there's an OSS driver which works - or any other, for that matter!
thanx

I havent used OSS in a long time so I dont know...have you unmuted the volume in the mixer? Everythings is muted by default...sometimes...

It's common among alot of Acer Aspire models. You will need to install the latest alsa drivers from CVS. Due to the architecture of the computer, older drivers don't work. I installed Ubuntu 5.10 and had video working otob. Good luck!
