Hi,
I have a problem using dmix on my embedded system (manual installation of alsa-lib 1.0.15)
When I play a sound with aplay, it works well.
When I try -D dmix or -D plug:dmix parameter, it doesn't work.
The output is:
aplay: main:547: audio open error: Operation not permitted
strace will help you. I would look to ipc permissions (alsa.conf):
defaults.pcm.ipc_gid audio defaults.pcm.ipc_perm 066
Thanks, but I just want to know where I manage that for IPC? I created an audio group and my /dev/snd/* files are in this group and have 0660 as permissions.
