bluetooth sco: fixed the softvol open error
This fixes #SPEC-2125. The fix consists in specifying the number of channels in the softvol pcm configuration. When it is not set, the libasound detects a configuration mismatch (the default number of channels being 2), and attempts to remove the sotfvol control, which for unknown reason, (broken support on kernel side ?) randomly fails.
