Because JACK accesses the soundcard directly (bypassing dmix) by default. JACK is written for low latency professional audio use - it's not intended to share the soundcard with other apps. This is not a bug - it's by design. > Do I need to feed it the dmix device name with > "jackd -d alsa -P <dmix-device-name>" or something similar? > Yes, you can do that.
