Hi,

Please is it possible to restrict the hw params space for the plug plugin by some alsa configuration, so that it reports/accepts only a specific number of channels/specific sample format? I was not able to figure it out, I apologize if it's trivial :-)

Hi,

here's a quick example:

=== pcm.hubcap { type plug slave { pcm "hw:Loopback,1,0" rate 48000 format S16_LE } } ===
