Hi Fons. I disabled PA and Jackd, enabled all output channels in alsamixer, and opened Chromium 34 on the test page: http://rdmedia.bbc.co.uk/proms/test.html Chromium can use Alsa, but I also have a mapping problem.
Here's what's coming out of my 7.1 sound card (per jack): Lime green (front): left: "this is the left front channel" right: "this is the right front channel" Black (rear): left: "this is the centre front channel" right: "this is the left surround channel" Orange (center/sub): left: "this is the right surround channel" right: silence... Grey (side): left: "this is the left front channel" right: "this is the right front channel" Then I reactivated PulseAudio and its jackd module, and now all channels are correctly assigned, except for the same copy of front to side. Maybe you can try remapping Alsa channels in a custom Alsa config file, setting the ALSA_CONFIG_PATH environment variable to this file before starting Chromium: http://www.alsa-project.org/main/index.php/LibEnvVars -- Marc Sat, 19 Jul 2014 14:39:45 +0000, wrote: > On Sat, Jul 19, 2014 at 10:00:20AM -0400, Marc Lavallée wrote: > > > Here's how to do it on Linux.
