[alsa-devel] plans for fireworks driver

[Takashi Sakamoto]

Hi Doug,

I note that your system cannot communicate to your device via FFADO 
because the device is already used by my module. You can execute 
"modprobe -r snd-fireworks" if you want to use FFADO.

Mmm, interesting... I want to investigate after implementation of 
multichannel playback and capture.

Anyway I commit your log.

Then I hope you to try playback.I reccomend below process:
1. use alsamixer to change sampling rate that you hope
2. use jackd in usual way, or aplay with plughw interface
3. hear 1/2ch or not

Thanks
