Re: Hi, does someone use i810 onboard sound ?

Hi again Stas,

I should have replied to the list, sorry about that.

Ok, I've played with the value of 6000 and tried various possibilities
up to 120000, but the sound doesn't improve.

There is something fishy, it seems. The sound is composed of a lot of
little "clicks". When a high sampling value (~60000) is used, it sounds
like the clicks become shorter.

With dosamp a 44kHz stereo file sounds perfect.

I hope this helps

Regards,
Joël
