Description of problem: Version-Release number of selected component (if applicable): alsa-lib-1.0.12-2.fc6 How reproducible: Steps to Reproduce: 1. Configure intel8x0 sound card (Intel ICH [NVidia CK8]) 2. Try to play a 1-channel audio file using aplay Actual results: aplay fails to play: [steve@rivendell ekiga]$ aplay -D hw:1,0 voicemail.wav Playing WAVE 'voicemail.wav' : Signed 16 bit Little Endian, Rate 22050 Hz, Mono aplay: set_params:909: Channels count non available (this only affects mono audio - stereo works fine) Expected results: aplay should play the audio Additional info: This completely breaks Ekiga, which returns a very unhelpful "couldn't open audio device" message. Fedora 4 on the same hardware works fine, so this is functionality that has been removed/broken in ALSA.
You have to use the plughw device, so aplay -D plughw:1,0 voicemail.wav should works for you. btw. the default configuration should work too (aplay voicemail.wav).
This is a misdiagnosis - I've opened bug #230069 to address the real problem.
