The way I run JACK then sometimes 'xrun's occur. I tried to increase the buffer number and the buffer size, but the non-default numbers are not accepted:
This one works: $ jackd -d alsa -r 44100 -d hw:0 jackd 0.98.1 Copyright 2001-2003 Paul Davis and others. jackd comes with ABSOLUTELY NO WARRANTY This is free software, and you are welcome to redistribute it under certain conditions; see the file COPYING for details loading driver .. 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 Couldn't open hw:0 for 32bit samples trying 24bit instead Couldn't open hw:0 for 24bit samples trying 16bit instead This one fails $ jackd -d alsa -r 44100 -d hw:0 -p 2048 jackd 0.98.1 Copyright 2001-2003 Paul Davis and others. jackd comes with ABSOLUTELY NO WARRANTY This is free software, and you are welcome to redistribute it under certain conditions; see the file COPYING for details loading driver .. apparent rate = 44100 creating alsa driver ... hw:0|hw:0|2048|2|44100|0|0|nomon|swmeter|-|32bit control device hw:0 configuring for 44100Hz, period = 2048 frames, buffer = 2 periods Couldn't open hw:0 for 32bit samples trying 24bit instead Couldn't open hw:0 for 24bit samples trying 16bit instead ALSA: cannot set number of periods to 2 for playback ALSA: cannot configure playback channel cannot load driver module alsa This one, too $ jackd -d alsa -r 44100 -d hw:0 -n 4 jackd 0.98.1 Copyright 2001-2003 Paul Davis and others. jackd comes with ABSOLUTELY NO WARRANTY This is free software, and you are welcome to redistribute it under certain conditions; see the file COPYING for details loading driver .. apparent rate = 44100 creating alsa driver ... hw:0|hw:0|1024|4|44100|0|0|nomon|swmeter|-|32bit control device hw:0 configuring for 44100Hz, period = 1024 frames, buffer = 4 periods Couldn't open hw:0 for 32bit samples trying 24bit instead Couldn't open hw:0 for 24bit samples trying 16bit instead ALSA: cannot set number of periods to 4 for playback ALSA: cannot configure playback channel cannot load driver module alsa What am I making wrong? _______________________________________________ haskell-art mailing list [email protected] http://lists.lurk.org/mailman/listinfo/haskell-art
