[gst-devel] ALSA Problem

[Steve Brown]

Thomas,

Here is the alsa gdb dump and debug output you requested.

I am running alsa 5.10b. This version is a little tricky to get running.
You have to have either devfs disabled in .config or fully running
(devfsd). Enabled and not running causes alsa to not create devices.

Thanks for looking at this. This is not a big deal, as alsa's oss
emulation seems to work fine.

Steve
