 Hello

 I have a problem with an external Trust USB Audio card. The card worked
 perfectly in the pre-PA world, but now the volume control doesn't work, it
 has absolutely zero effect. It turns out that there are two channels named
 "speaker", but only one of them affects the output level, and PA adjusts
 the wrong one.

 It seems that the problem of weird mixer controls is rather prevalent. I
 experienced a similar problem with my internal sound card (where Master
 doesn't affect Headphone) but was told it was an ALSA problem.
