...nk there's one missing for multichannel configurations. There should be a value for mapping the individual channels to spatial locations. Lets assume a Vorbis stream contains 4 channels, two front channels and two back channels, then the corresponding comment value could be CHANNELS=FRONT_LEFT,FRONT_RIGHT,BACK_LEFT,BACK_RIGHT where the first value corresponds to channel 0, the second to 1 and so on. Using the following values for channel mappings would allow a 1:1 translation with DirectShow: FRONT_LEFT FRONT_RIGHT FRONT_CENTER LOW_FREQUENCY BACK_LEFT BACK_RIGHT FRONT_LEFT_OF_CENTER FRONT_RIGHT_O...

...handle sound. I installed it and fired it up. Out of the box it didn't work. But I simply had to choose the correct device from audacity's drop-down menu and, viola, it would produce sound from a loaded file. Cool. Right after that, I tried running "aplay /usr/share/sounds/alsa/Front_Right.wav" and that worked. Previously it didn't, although (as noted above) that same command when specifying the device did (i.e., "aplay /usr/share/sounds/alsa/Front_Right.wav -D plughw:0"). So apparently installing and/or running audacity fixed something, but not everything....

...ampo suggested. This is basically the same thing as the "channel map" described on the wiki, but with the (physical,logical) channel pair swapped. So, using the syntax from the wiki: channel_type = OGG_CHANNEL_MAP_STEREO channel_map [OGG_CHANNEL_FRONT_LEFT] = 1 channel_map [OGG_CHANNEL_FRONT_RIGHT] = 2 This is nice because it makes it impossible for somebody to do something stupid like define two channels as carrying FRONT_LEFT. A player can't handle that situation sanely, but handling both FRONT_LEFT and FRONT_RIGHT mapping to channel 0 is easy. Like Sampo said, this does mean havi...

Remember that channel_map is just an array (unless you want to make it a map?). So if you had a OGG_CHANNEL_SPECIAL with an id of 1000, it would force 1000 entries in the array. > This is nice because it makes it impossible for somebody to do something >...
