Description Dmitry Lukhtionov 2017-03-23 10:27:40 UTC
During boot, I see these lines in my messages file:

Mar 23 11:35:29 m18 pulseaudio[1109]: [(null)] oss-util.c: '/dev/dsp0' doesn't support full duplex

# cat /dev/sndstat
Installed devices:
pcm0: <Intel Haswell (HDMI/DP 8ch)> (play)
pcm1: <Realtek ALC887 (Rear Analog)> (play/rec)
pcm2: <Realtek ALC887 (Front Analog)> (play/rec) default
No devices installed from userspace.

and

# ls -al /dev/dsp*
crw-rw-rw-  1 root  wheel  0x92 23 марта 11:35 /dev/dsp0.0
crw-rw-rw-  1 root  wheel  0x94 23 марта 11:35 /dev/dsp1.0
crw-rw-rw-  1 root  wheel  0x96 23 марта 12:00 /dev/dsp2.0


Why device /dev/dsp0.0 have RW permission ?

Closing this as sound(4) no longer creates devices for individual channels.
