I am trying to output pulseaudio out to my stereo by encoding it into a52 format using the a52 plugin for alsamixer. This is fairly normal as pulseaudio detects that I have the a52 plugin setup and will display the option for 5.1 sound output via the gnome sound preferences. 

This is useful for playing games that support more then 2 channels audio and your using a home theater type system that supports a52 audio over SPDIF. Even the very cheap ones support this.

from dmesg.
[  203.832068] alsa-sink[1988]: segfault at 20 ip 00007fcbcb696243 sp 00007fcbc99d2b80 error 4 in libavcodec.so.52.113.2[7fcbcb384000+525000]

That happens every time I try to enable digital surround sound via sound preferences. Looks like it's a segfault in the a52 plugin itself or something. I don't know for certain.

The normal PCM digital out works, but that's only 2 channels.

$ cat /etc/asound.conf 
#
# Place your global alsa-lib configuration here...
#

@hooks [
	{
		func load
		files [
			"/etc/alsa/pulse-default.conf"
		]
		errors false
	}
]

		pcm {
			type a52
			bitrate 448
			#bitrate 640
			channels 6
			card $CARD
		}
	rate 48000 #required somehow, otherwise nothing happens in PulseAudio
	}
}

Comment 6 Fedora End Of Life 2012-08-07 16:55:05 UTC
This message is a notice that Fedora 15 is now at end of life. Fedora
has stopped maintaining and issuing updates for Fedora 15. It is
Fedora's policy to close all bug reports from releases that are no
longer maintained. At this time, all open bugs with a Fedora 'version'
of '15' have been closed as WONTFIX.

(Please note: Our normal process is to give advanced warning of this
occurring, but we forgot to do that. A thousand apologies.)

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, feel free to reopen
this bug and simply change the 'version' to a later Fedora version.

Bug Reporter: Thank you for reporting this issue and we are sorry that
we were unable to fix it before Fedora 15 reached end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora, you are encouraged to click on
"Clone This Bug" (top right of this page) and open it against that
version of Fedora.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

The process we are following is described here:
