Subject: [PATCH 0/2] alsa-lib surround 2.1 support
Date: Tue, 18 Feb 2014 16:41:47 +0100 [thread overview]
Message-ID: <1392738109-9956-1-git-send-email-david.henningsson@canonical.com> (raw)
I'm currently experimenting with different ways to make the system autodetect
if surround2.1 is available through a four channel setup (e g laptop surround
speaker) and fallback to 5.1 if it isn't.
It's a bit tricky, especially given that the LFE speaker could be on left channel,
right channel, and both, so meanwhile, this fallback should be better than nothing
and help establish a standard for upper parts of the stack (i e PulseAudio).
