Sound is working quite fine in stereo mode, but if I want to play a DVD with 5.1 sound, all speakers are activated but the sound is a little bit distorted. xine uses plug:surround51:0 as the surround device. My asound.conf looks like this: pcm.!default { type plug slave.pcm "svol" } pcm.svol { type softvol slave.pcm "hw:0,0" control { name "PCM Playback Volume" } } I also tried the one from http://www.sabi.co.uk/Cfg/ALSA/ Again, stereo sound works fine and also dmix does its work, but this time I only get stereo sound in xine although the same configuration of xine is used. I also noticed that playing some files using aplay produces the same distortions, e.g.: aplay /usr/share/sounds/k3b_success1.wav Playing WAVE '/usr/share/sounds/k3b_success1.wav' : Unsigned 8 bit, Rate 8000 Hz, Mono Seems to have to do something with sample rate. Using the other asound.conf from the homepage above just gives an error: Playing WAVE '/usr/share/sounds/k3b_success1.wav' : Unsigned 8 bit, Rate 8000 Hz, Mono aplay: set_params:857: Sample format non available Is there a way to play 5.1 sound without these distortions? Maybe some lines added to my asound.conf would do the work. Thanks in advance!

The sound still gets sometimes distorted, but only ocasionaly and for a moment only. ---------------------------------------------------------------------- rlrevell - 12-19-05 07:59 ---------------------------------------------------------------------- Would you say this bug is fixed?
