Description

Hi, previously, in solaris 10, installing OSS drivers, I can use separately the different outputs of my multi-channel sound card. But in Illumos distro the sound card is recognized and works but only have one device.

This is the solaris 10 output of 'cat /dev/sndstat'

-bash-4.3# cat /dev/sndstat
OSS 4.2 (b 2011/201501280019) (C) 4Front Technologies 1996-2011

Audio devices:
0: HD Audio play front (OUTPUT)
1: HD Audio play center/LFE (OUTPUT)
2: HD Audio play rear (OUTPUT)
3: HD Audio rec rec1mux (INPUT)
4: HD Audio rec rec2mux (INPUT)

MIDI devices:

Mixers:
0: High Definition Audio STAC9221 A1

NOTICE! Device numbers shown above may be wrong.
Use the ossinfo command to find out the correct device names.

and from illumos:

root@xxxxxx:/root# cat /dev/sndstat
SunOS Audio Framework

Audio Devices:
0: audiohd#0 Intel HD Audio, ICH7 (DUPLEX)

Mixers:
0: audiohd#0 Intel HD Audio, ICH7
HD codec: Sigmatel STAC9220D

then, how can I send audio to a specific output?

Thanks in advance.
