Hi.

My soundcards:
$ lspci |grep media
0000:00:07.5 Multimedia audio controller: VIA Technologies, Inc. VT82C686 AC97 Audio Controller (rev 20)
0000:00:0b.0 Multimedia audio controller: C-Media Electronics Inc CM8738 (rev 10)
$ cat /proc/asound/cards
0 [CMI8738        ]: CMI8738 - C-Media PCI CMI8738
                     C-Media PCI CMI8738 (model 37) at 0xc000, irq 10
1 [rev20          ]: VIA686A - VIA 82C686A/B rev20
                     VIA 82C686A/B rev20 with ALC100,100P at 0xac00, irq 10

I use version from experimental because I need dmixing to work in
multi-user environment. Nevertheless, this report applies to both
unstable and exp. versions.

I try to describe the bug (or feature?) on an example:

$ aplay -D default:1 somefile.wav
...plays sound on VIA

on the second terminal
$ aplay -D default:0 somefile.wav
...plays sound on VIA too, I think it'd use on CMI

Using hw instead of default works right. However, I need dmixing on both
devices. I think this should be default behavior, not something to fix
by custom asound.conf file.
