Hello,
I am using snd-bt-sco with my headset, and I noticed that every time that
snd-bt-sco kernel module is loaded, I cannot suspend to ram or to disk
using ACPI due to the error bellow.
I seems that snd-bt-sco refuses to sleep.
Has anyone experienced this, or is my setup broken ?
Thx.

your setup is fine, but the snd-bt-sco is broken. The kernel thread is
active blocking and I think the locking is also wrong. The goal is a
ALSA library plugin for the headset support and I am not going to fix
any part of the snd-bt-sco kernel driver.
Regards
Marcel
