[pulseaudio-discuss] 7.1 surround problem

[Brendon Costa]

Hi all,

I have an app that is using the async interface of pulse that comes
with Ubuntu 10.04

Server Version: 0.9.21-63-gd3efa-dirty
Linked to Library Version: 0.9.21-63-gd3efa-dirty
Compiled with Library Version: 0.9.14

The sink info structure reports that it has 8 channels available
(which is expected as it is using a 7.1 surround sound device). I find
that if I try to open a stream to the sink with 1 - 6 channels
everything works as expected, but if I try to open 7 or 8 channels,
then pa_stream_new() returns NULL with "Invalid argument" set in the
context errno.

Are there any known issues with using Pulse with a 7.1 surround system?

If not, I can post some code that returns the error if that will help
(it is a stand alone test app, but is large and a little messy at the
moment).

Thanks,
Brendon.
