I've duplicated your suggested lines, in the hope that this would relay the wave data from the soundcard without reencoding. I replaced the alsa device name with the first device name which shows up when I run pacmd list-sources ...as the mpd user, the name of this device being... alsa_output.usb-0d8c_C-Media_USB_Headphone_Set-00-Set.analog-stereo.monitor Inspecting the soundcard through Alsa tools suggests that the hardware shows up as... mpd@gardner:/root$ cat /proc/asound/card0/pcm0p/sub0/hw_params access: MMAP_INTERLEAVED format: S16_LE subformat: STD channels: 2 rate: 44100 (44100/1) period_size: 44100 buffer_size: 88200 ...so I'm guessing the mime type information matches with the declaration you provided too. Having launched rygel (logged in as the mpd user) and when trying to stream using VLC on my desktop from the detected endpoint (which appears correctly), rygel reports the sync error as normal when the stream starts but doesn't report a critical Gstreamer error, so I guess it's doing something. In all the incorrect configurations so far, the stream died immediately, so this is something like progress. However, I get VLC reporting 00:00 seconds in the stream and no sound audible. Are you able to stream audible sound to VLC using the configuration you shared with me? Thanks for all your help. I would have given up long ago without confident guidance on this. I've attached my current rygel configuration and the pacmd report on my devices in case anything leaps out which needs to be differently configured. Cefn http://cefn.com
