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.
