Thsi has nothing to do with the sample rate, but with the period size. There also could be an error "snd_pcm_hw_params_set_rate", that would be samplerate-related. Actually I now tried ogg123's alsa support for the first time and I get this same error regardless of what file I try to play. The ogg123 manpage reveals, that ogg123 can only set the card to use by number, like "ogg123 -d alsa09 -o card:0 -o dev:0 ..." This is bad and actually it should be possible to specify device by name, because that's what the documentation for libao says. (libao is used by ogg123 for audio output). But it isn't possible, so you can either wait until the Ogg developers fix this, use ALSA's oss-emulation or try playing with the buffer size option. I use OSS-emu. ciao -- Frank Barknecht _ ______footils.org__ ------------------------------------------------------- This SF.net email is sponsored by: eBay Get office equipment for less on eBay! http://adfarm.mediaplex.com/ad/ck/711-11697-6916-5 _______________________________________________ Alsa-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-user
