[Alsa-user] speaker-test sees only 1 channel

[<g.h...@ve...>]

Underal alsamixer there are a left and right channels, as well as LFE and 
Surround settings.

But speaker-test reports that there is only 1 channel on my sound card:

speaker-test 1.0.7

Playback device is plughw:0,0
Stream parameters are 48000Hz, S16_LE, 1 channels
Sine wave rate is 440.0000Hz
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 128 to 32768
Period size range from 32 to 32768
Buffer time size 24000
To choose buffer_size = 24000
To choose period_size = 3000
was set period_size = 3000
was set buffer_size = 24000

Is there a way to fix this? Is it even an ALSA problem?
