Hello,

I have been having a slight problem with jack and qjackctl. I would
like to set jack to run at 44100 rate instead of the default of 48000
but I am getting excessive xruns. here is the messages from qjackctl
when started:

apparent rate = 44100
creating alsa driver ... hw:0|hw:0|1024|2|44100|0|0|nomon|swmeter|-|32bit
control device hw:0
configuring for 44100Hz, period = 1024 frames, buffer = 2 periods
Note: audio device hw:0 doesn't support a 32bit sample format so JACK
will try a 24bit format instead
Note: audio device hw:0 doesn't support a 24bit sample format so JACK
will try a 16bit format instead
nperiods = 2 for capture
Note: audio device hw:0 doesn't support a 32bit sample format so JACK
will try a 24bit format instead
Note: audio device hw:0 doesn't support a 24bit sample format so JACK
will try a 16bit format instead
nperiods = 2 for playback
playback and capture sample rates do not match (48000 vs. 44100)
**** alsa_pcm: xrun of at least 0.024 msecs
**** alsa_pcm: xrun of at least 0.023 msecs
**** alsa_pcm: xrun of at least 0.025 msecs

as you can see there is a playback/capture rate mismatch. does anyone
know how I can fix this. please keep in mind I am a bit of a linux
newbie so please be specific on commands and paths please.

thanks
