Nvidia MCP51 High Definition Audio

[mumbo719]

Greetings all!

I have been on Mint for a month now and finally found a distro that allowed me to delete Windows.

Thanks Clem and Gang!

Everything works except my sound, I get a high pitched squeal/hissing sound along with the sound from the media I am playing. I have googled and googled and tried a few things but found no solution.

From my device manager it shows I have the Nvidia Nvidia MCP51 High Definition Audio on my AMD Athlon X2 machine.

Any help is appreciated.

A few ideas..

- see if you have some bluetooth stuff activated (I had a similar problem in KDE..)
- play with the mixer, in particular with the switches (in preferences, add everything, then in switches turn on/off everything while you've got the music playing).

Thanks Clem, When I turn everything off and on again in the mixer I lose all audio till I reboot the machine.

Blue tooth is inactive at startup according to the service setting manager in Mint Config.

Thanks again.

hmm this is weird, maybe it's a hardware/driver problem. I'm afraid I can't help much on that..

No go, it seems this sound card is not supported very well in Linux at the moment.

I'll try again tomorrow

If you are feeling especially adventurous, you could download the latest beta release of alsa and compile it.

If you go that route and have any questions, go ahead and post here and I'll get you through it.

That should get the sound working.

Either that or spend about $20 for a standalone card like the Chaintech AV-710 which is very well supported in linux.

Here is a link to a sound card roundup under linux. For those that don't know, Phoronix is a linux hardware/software review site.

I had the same problem, I downloaded and installed the latest alsa-driver snapshot ftp://ftp.suse.com/pub/projects/alsa/sn ... 10.tar.bz2 and sound is working fine now.

cheers
