Yes this should be correct. ADAT optical does only support up to 48KHz per channel, thus the card switches on 96KHz into double speed mode, which means, that the data for a single channel is transmitted over two channels. This means that the channel count is cut to half. > I opened a topic on the RME-Linux-Forum a while ago: > https://www.forum.rme-audio.de/viewtopic.php?id=17373 > > While regarding the sources, i realized (i am at no means a > coder/dev/whatever, so...) > that in the hdspmixer the channelmap is missing for the HDSP9652, but > for the other cards (Digiface, Multiface, RPM...) Channelmpas are specified. Maybe you are using an old version? I found a matching mapping right here for alsa-tools version 1.0.29 : https://fossies.org/dox/alsa-tools-1.0.29/channelmap_8cxx_source.html#l00099 ------------------------------------------------------------------------------ _______________________________________________ Alsa-user mailing list Alsa-user@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/alsa-user
