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. -------- Original Message -------- Subject: Re: Patch review Date: Mon, 21 Mar 2011 17:42:07 +0300 From: Daniel Chen <seven.st...@gmail.com> To: Moustafa Chamli <moustafa.cha...@canonical.com> 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.
