Thank you. Where those hw numbers come from? I tried the following under Gnome:
# speaker-test -t wav -c 2 -D hw:0,0
speaker-test 1.0.25
Playback device is hw:0,0
Stream parameters are 48000Hz, S16_LE, 2 channels
WAV file(s)
Playback open error: -16,Device or resource busy
# /etc/init.d/pulseaudio stop
[warn] PulseAudio configured for per-user sessions ... (warning).
# speaker-test -t wav -c 2 -D hw:0,0
speaker-test 1.0.25
Playback device is hw:0,0
Stream parameters are 48000Hz, S16_LE, 2 channels
WAV file(s)
Playback open error: -16,Device or resource busy
# speaker-test -t wav -c 2 -D hw:1,0
speaker-test 1.0.25
Playback device is hw:1,0
Stream parameters are 48000Hz, S16_LE, 2 channels
WAV file(s)
Playback open error: -2,No such file or directory
# speaker-test -t wav -c 2 -D hw:2,0
speaker-test 1.0.25
Playback device is hw:2,0
Stream parameters are 48000Hz, S16_LE, 2 channels
WAV file(s)
Playback open error: -2,No such file or directory
Just wondering what change does in second number:
# speaker-test -t wav -c 2 -D hw:0,1
speaker-test 1.0.25
Playback device is hw:0,1
Stream parameters are 48000Hz, S16_LE, 2 channels
WAV file(s)
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 64 to 16384
Period size range from 32 to 8192
Using max buffer size 16384
Periods = 4
was set period_size = 4096
was set buffer_size = 16384
0 - Front Left
1 - Front Right
Time per period = 2,730392
0 - Front Left
1 - Front Right
Time per period = 2,986731
0 - Front Left
1 - Front Right
Still no sound. So no success.
