Description of problem: The alsa jackplug no longer works. It worked in previous fedora versions of alsa, but I can't give a version number. When the jackplug is configured as: pcm.jackplug { type plug slave { pcm "jack" } } pcm.jack { type jack playback_ports { 0 alsa_pcm:playback_1 1 alsa_pcm:playback_2 } capture_ports { 0 alsa_pcm:capture_1 1 alsa_pcm:capture_2 } } And tested with aplay: aplay -Djackplug /usr/share/sounds/purple/receive.wav The following error is produced: aplay: set_params:900: Sample format non available Version-Release number of selected component (if applicable): alsa-lib-1.0.14-3.fc7 How reproducible: always Steps to Reproduce: 1. Configure jackplug in .asoundrc as above 2. Test using aplay -Djackplug <some .wav file> Actual results: aplay produces the following error message: aplay: set_params:900: Sample format non available Expected results: aplay should route sound into the jack audio connection kit. Additional info: This is an alsa configure script bug and has been described here: https://bugs.launchpad.net/ubuntu/+source/alsa-lib/+bug/148510 http://hg-mirror.alsa-project.org/alsa-lib/rev/917d1281c93f
Please report it to ALSA project (www.alsa-project.org). Seems to be related to sound config for your sound card where some plugins are missing (probably the rate plugin?)
