i has VIA8235 and ALC650 codec. After installing new driver from cvs from
20030113, there is following problem:

In 5.1-channel dvd playback with xine using surround51 device,
i has swapped Rear and Center/lfe channels.
RL <-> Center, RR <-> LFE
i fixed this with following patch for via82xx.c

812,813c812,815
<       case 5: slots = (1<<0) | (2<<4) | (5<<8) | (3<<12) | (4<<16); break;
<       case 6: slots = (1<<0) | (2<<4) | (5<<8) | (6<<12) | (3<<16) | (4<<20); break;

please note that 5ch mode is untested.
I'm not sure that it is alsa problem, xine' may be.
It will be nice to have a small prog for channel position testing in different
playback modes, because now i know no 5.1ch source other then video player.
In general multichannel playback has good quality now (with rc6 sound was
cracking).

It's worked, but second stream plays only left channel.

Almost all OSS application such as games (UT, tux-racer and other) now producing
cracking and skipping sound. Only XMMS OSS-plugin plays good. OSS-sound was good
with rc6.
