I'm not sure I entirely understand your bug report.
Can you run jackified clients at 192kHz? Let's say mplayer -ao jack or
Or do you mean that you cannot run other ALSA applications when jackd is
running (at 192kHz)? If so, this would be perfectly normal. I even
wonder that it works at lower samplerates.
Think of exclusive device access for jackd. Everything else needs to be
routed through jackd. This situation will be improved with jackd2 and
pulseaudio: when jackd2 is starting, it acquires the card from
pulseaudio, and pulseaudio would insert the jack modules to output the
sound via underlying jackd2.
Also note that jackd2 is intended for professional audio, especially as
an inter- and intra-application-framework for low latency audio
production. You don't need it if you're not doing music production. ;)
So please clarify the problem.
