I'm checking with the xorg ati list to see if they have any info.

It all works for a while, but eventually I'll get a "azx_get_responsetimeout, switching to polling mode: last cmd=0x10bb2001" and it nolonger responds to headphone plug events without an unload/reload ofthe module._______________________________________________Alsa-devel mailing listAlsa-devel@xxxxxxxxxxxxxxxxxxxx://mailman.alsa-project.org/mailman/listinfo/alsa-devel
