This message indicates that PulseAudio could not find out an ALSA device that opens and provides the correct channel map without the plug layer. You can look into /usr/share/pulseaudio/alsa-mixer/profile-sets/default.conf to see which device strings are tried with which channel map. Also please note that there was an important improvement in PulseAudio 6.0 regarding devices that can only be opened with the "hw:X" device and with more than two channels. Previously, they would produce an error message that is the same as yours. So maybe it is a good idea to try the latest version? If that doesn't help, then we need more information about the hardware. Is it a stereo or multichannel card? Is it a USB audio card? If it can do 5.1 audio, what does the following command produce? aplay -vv -f dat -d 1 -D surround51:9 /dev/zero -- Alexander E. Patrakov
