Ubuntu 12.04 5.1 / 7.1 sound mapping pulseaudio problem - gerner - 2012-07-06 Hello folks, I'm in the ubuntu sound configuration cloud of confusion and hoping someone may be able to help. I'm trying to get my new 5.1 / 7.1 system set up with pulseaudio. Problems 1. I can't get pulseaudio to get my channel mappings right. 2. Playing a DVD the sound device failed to initialise - works fine for ac3 - some sort of passthrough vs decoding to pcm issue? Hardware: I've just bought a Yamaha YSP-2200 soundbar AV receiver and am trying to get it working with XBMC over HDMI. I'm using a first gen ION board, alsamixer tells me my sound hardware is a Nvidia MCP79/7A HDMI. Attempted solution Following wiki instructions has got me so far. ALSA has my 5.1 channel mappings all sorted correctly using this ~/.asoundrc Code: pcm.!default { If I kill pulseaudio before I start my XBMC session, and configure XBMC to use hdmi-remap and ALSA as the output / passthrough devices, then everything plays nicely, apart from menu sounds. The problem is if I don't kill pulseaudio then the hdmi-remap device is busy. I did some poking about and discovered pulseaudio had it locked. Any ideas what direction I should be going in? I'm not sure if I should be trying to 'redirect' pulse audio to use the hdmi-remap device, or if I should just uninstall pulseaudio (notwithstanding menu sounds issue)? Or if there's some other issue at play, e.g. pulseaudio doesn't offer a 7.1 option, which may be causing the channel mapping issue. TIA for any help. RE: Ubuntu 12.04 5.1 / 7.1 sound mapping pulseaudio problem - DaVu - 2012-07-07 I had some sound problems too after a "screenshot-software" installed pulseaudio packages (for what ever). I had menu sounds but after starting a movie I got the error "unable to intialise sound" or similiar. apt-get purge pulseaudio helped for me. So I donĀ“t need menusounds and I can deal with it. Greetings RE: Ubuntu 12.04 5.1 / 7.1 sound mapping pulseaudio problem - gerner - 2012-07-10 Just an update for future googlers. For the channel mapping issue I found how to remap channels in pulseaudio here: http://confignewton.com/?p=211 From what I can make out it's not possible to use passthrough with pulseaudio with a stock Eden 11 xbmc. Apparently you can purge pulseaudio and use ALSA, but I'm toying with trying a nightly build. I may just leave as is for now and ignore the passthrough - still not sure how much I'll benefit from passthrough. |
