The gnome volume control keeps resetting the channel mode setting to 2ch instead of 6ch as asked to. This doesn't smell like Pulseaudio is at fault, reassigning to the kernel, thinking this is the ALSA driver but I'm unaware how to get more information. Which kernel version? And did you try completely disabling pulseaudio to rule it out? Uninstalling pulseaudio and pulseaudio-plugins-alsa should be enough. kernel-2.6.23.1-37.fc8 Removing all of PulseAudio still only yeilds stereo output interestingly, the same thing happens when I plug in this newly bought Sound Blaster Surround 5.1 USB card when connected to the speakers using a TOSLINK cable. I tested the speaker arrangement by plugging it directly into my DVD player using the TOSLINK and that played back DTS 5.1 beautifully. Currently, PulseAudio opens audio devices in Stereo only by default. You need some manual configuration to actviate surround support. The reason for this is PA can hardly guess how many boxes you actually connected to your PC and how they are positioned in your room. I am working to make this a bit easier to configure, i.e. by right clicking on a device in pavucontrol, and selecting from a small popup menu your setup from a couple possible setups. (i.e. "Analog Stereo", "Analog 4.0", "Analog 4.1", "Analog 2.1", "Analog 5.1", "Digital" and so on). Stay tuned. Oh, and this in fact is a limitation of PA and probably has nothing to do with the kernel. And also, please not that PA only very unlikely will ever do AC-3 encoding for you, due to patents. So long as I can do AC3 passthrough I believe the hardware I have will do the actual decoding for me. Lennart, is there any progress in providing some UI to set this. One problem that occures from this is that video files contain AC3 sound is that the audio gets directed to the wrong channels using Totem I only have what sounds like the center channel directed out the left speaker.. entirely unusable in other words. Playing the same file with mplayer the audio gets down sampled to 2 channels correctly (though the volume is very low). I have a SB-Live 24-bit usb external card as well. I have only tried stereo output through the coax-digital output, but it only works when I connect the usb device before booting the system. If I connect it after the system boots the only thing I get through the digital coax out is the little start-up sound and then nothing. aplay will not even show the iec958 device, but using the surround71 device will result in 2-channel audio played out through the coax port. Something else is going on here and I don't think this is only pulseaudio's fault :) I'm still looking into the various problems I am seeing. I also find that the analog line outputs do not work at all, but the headphone jack does. Changing version to '9' as part of upcoming Fedora 9 GA. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping OpenSUSE 11 now has the UI for doing this: http://dev.compiz-fusion.org/~cyberorg/2008/06/02/opensuse-touch-to-pulseaudio/ Reassigning to rawhide as there still isn't UI to change this. Lennart can you comment on the openSUSE patch? This bug has been triaged TheOpenSUSE patch is a too limited and makes a per-device setting global. I don't think it is a good idea to merge that. This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle. Changing version to '10'.
