Comment 16 for bug 1074783

When I do this command for (HDA Intel) 0:
speaker-test -c 2 -D plughw:0 -t sine

Only through my laptop's right-internal-speaker do I hear sound. The left one doesn't work.

When I do this command for (USB Audio Device) 1, I do not hear sound from any speaker:
speaker-test -c 2 -D plughw:1 -t sine

speaker-test 1.0.25

Playback device is plughw:1
Stream parameters are 48000Hz, S16_LE, 2 channels
Sine wave rate is 440.0000Hz
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 96 to 268435
Period size range from 48 to 134218
Using max buffer size 268432
Periods = 4
was set period_size = 53686
was set buffer_size = 268432
 0 - Front Left
 1 - Front Right

And lastly, if I try (USB Device 0x46d:0x821) 2, I get an error

speaker-test -c 2 -D plughw:2 -t sine

speaker-test 1.0.25

Playback device is plughw:2
Stream parameters are 48000Hz, S16_LE, 2 channels
Sine wave rate is 440.0000Hz
Playback open error: -2,No such file or directory
