I'm trying to use the alsa jack plug to route audio though a jack server. I followed the instructions here: http://alsa.opensrc.org/index.php/Jack_(plugin) My .asoundrc contains the settings given on that page. I start the jack server just fine: $ jackd -d alsa hw:0 -r 44100 & [1] 3222 jackd 0.103.0 Copyright 2001-2005 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 JACK compiled with System V SHM support. 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 ALSA: final selected sample format for capture: 16bit little-endian ALSA: use 2 periods for capture ALSA: final selected sample format for playback: 16bit little-endian ALSA: use 2 periods for playback But when I start aplay I get: $ aplay -D pcm.jack /usr/share/sounds/phone.wav JACK tmpdir identified as [/dev/shm] Playing WAVE '/usr/share/sounds/phone.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo aplay: set_params:901: Sample format non available I couldn't find anything in the archives or using google regarding this specific problem.
