Bug#514260: linux-image-2.6.26-1-amd64: kernel does not support multiple, not similarm soundcards

Hi Ben,

Thanks for the reply.
Situation is as follows:
my motherboard has an onboard soundcard. I own several PCI card soundcards. I tried them all, all to the same result. If I have besides the onboard card one PCI soundcard in the system (so 2 soundcards in total) the sound system does not give a sound at all on any card. All mixer settings are lost. I have to run "alsaconf" on every occasion to enable sound on the onboard card. IIRC (but it has been a while since I tested) sound on the PCI cards never works.
The issue seems to be driver related as dmesg contains errors before I do a thing. I think the issue kicks in the moment the driver for a PCI card is loaded and it starts conflicting with the onboard card.
On the first releases of 2.6.26 stock kernel things worked fine. All kernels since then / up till now have this issue including the kernel currently shipped with Lenny.

Sorry for the delay in answering your bug report.

Do you mean that mixer settings are not correctly restored to two cards
of one type?
