Description Tanu Kaskinen 2012-05-08 19:51:20 UTC 
This fails:
pactl load-module module-null-sink channel_map=aux0,aux1,aux2,aux3

Thid doesn't fail:
pactl load-module module-null-sink channel_map=aux0,aux1,aux2,aux3 channels=4

Both should succeed. In the first case it's obvious that the intended amount of channels is 4. The problem is that pa_modargs_get_sample_spec_and_channel_map() fails if "channels" is not given and the default sample spec channels don't match the given channel map. pa_modargs_get_sample_spec_and_channel_map() needs to be smarter than that.
