Hello,

I had spoken with Daniel Chen about LP bug #178442

Below is his comment on the issue.

Could you give it a look?

Cheers.

Hi Moustafa,

The root issue is that alsa-lib's "front" (playback-only) virtual
definition for the ice17* (among others), which PulseAudio prefers and
uses by default, should be set as the maximum playback channels, which
is 10. Upstream ALSA has not reached a conclusion whether this is the
correct approach, and upstream PulseAudio has been resistant to work
around this issue in PA (see http://pulseaudio.org/ticket/624).

My opinion has long been that it should be resolved in alsa-lib, and
several attempts have been made to no avail. It is worth raising again
via David H (hardware enablement Canonical kernel team).

At best the profile sets in the attachments in upstream PA bug 624 are
workarounds and need verification from ice17* users (who, despite
seeming vocal, constitute a minority of PA users). It is likely that
additional tweaking will be necessary.

My suggestion is to raise this issue on the ubuntu-audio-dev Launchpad
mailing list (please feel free to forward this response there, as I am
deployed currently and won't return to Ubuntu development until midway
through the 11.10 development cycle), where a consensus can be reached
quickly regarding what to do for 11.04.

Best,
-Dan
