Subject: Split a 7.1 device into 4 stereo devices
Date: Tue, 08 Jul 2014 17:18:11 +0200	[thread overview]
Message-ID: <1404832691.13359.9.camel@X230> (raw)


Hello,

I have a 7.1 sound device and speaker-test -c8 can output on each
speaker. But what I would like to do is using it as 4 stereo devices so
I could play different sounds on each of them.

Ideally I would like to avoid dmix and friends to be able to have
gapless and bit-perfect output.

On IRC "debianuser" said it is possible with hdajackretask to make it
appear as 4 different hw devices in "aplay -l" but we didn't succeed
doing that. Anyone knows what configuration is needed for that?

Here is my setting:

Regards,
Xavier Claessens.
