Hi All, I've installed ALSA 1.0.19 on a fresh install of Mythbuntu 8.10 on two seperate machines, and I am trying to get digital audio pass through to work properly. One machine with an ALC888 soundcard with SPDIF output, and the other with a VT1708B soundcard with HDMI output. I have digital output working using the mplayer "-ao alsa:device=spdif" or "-ao alsa:device=hdmi" commands respectively, and the Dolby Digital and DTS indicators light up on my receiver that it is getting a valid digital audio stream. Ultimately I know it works as I can hear the audio tracks in my movies. The problem I am having is that I only seem to be getting 2 channels on both machines, and not only in mplayer as I've tested using speaker-test and also MythDVD. Both these cards are capable of 7.1 sound, but ultimately I need to configure them to output 5.1 (as that is all the receivers they are being connected to are capable of). I've scoured the Internet, but don't seem to be able to find any information on configuring the number of channels for SPDIF output. Can someone please help me? ------------------------------------------------------------------------------ Open Source Business Conference (OSBC), March 24-25, 2009, San Francisco, CA -OSBC tackles the biggest issue in open source: Open Sourcing the Enterprise -Strategies to boost innovation and cut costs with open source participation -Receive a $600 discount off the registration fee with the source code: SFAD http://p.sf.net/sfu/XcvMzF8H _______________________________________________ Alsa-user mailing list Alsa-user@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/alsa-user
