Sound: change on_new_*_channel() signatures
Sound: change on_new_*_channel() signatures

Pass the new sound channel to these functions rather than setting
worker->connection before calling the function and expecting it to be
set when the function is called. The fewer unenforced assumptions that
must be true for a function to work properly, the easier it will be to
maintain.
