Hi. Under kernel 2.6.23, I could get sound from the alsa device created by the module snd_bt87x. In kernel 2.6.24, there is no sound. And yes, I have checked in alsamixer that the device is not muted. Also, in kernel 2.6.23 the device would only appear if I modprobed the module with the option load_all=1. In kernel 2.6.24, the option load_all=1 is unnecessary for the device to appear. This is probably because I have in 2007 sent an email to this list (http://mailman.alsa-project.org/pipermail/alsa-devel/2007-August/002617.html) with information about my board, and it was responded by Takashi. I have tried the latest linux-2.6.27-rc4 hoping the problem could have been fixed. No improvement. Could you please look at this? It is an important regression.
I have included extensive information about my system (under both linux-2.6.23, where my card works, and linux-2.6.27-rc4) in the tarball attached. If you need any other information please ask me.
