RHBA-2015:0655 - Bug Fix Advisory

Topic

Updated pulseaudio packages that fix several bugs are now available for Red Hat
Enterprise Linux 6.

Description

PulseAudio is a sound server for Linux and other Unix-like operating systems. It
is intended to be an improved drop-in replacement for the Enlightened Sound
Daemon (ESOUND).

This update fixes the following bugs:

• Previously, the pulseaudio(1) man page did not mention the PulseAudio cookie

file. As a consequence, if a user wanted to connect to the audio server but was
logged in with a different user and cookie, the connection failed, and it was
not clear from the documentation what the user must do. With this update, the
man page has been improved, and the necessary steps can be found there.
(BZ#812444)

• Prior to this update, certain applications that require lower audio latency

produced low-quality sound when using the PulseAudio "combine" module. With this
update, the "combine" module uses automatically adjusted audio latency instead
of fixed high audio latency. As a result, sound quality is no longer affected
when using low-latency applications with the "combine" module. (BZ#1111375)

• Previously, the following warning message was displayed during the booting

process when using PulseAudio :

udevd[PID]: GOTO 'pulseaudio_check_usb' has no matching label in:
'/lib/udev/rules.d/90-pulseaudio.rules'

The invalid parameter that caused this problem has been removed from PulseAudio
udev rules, and the warning message no longer appears. (BZ#1110950)

Users of pulseaudio are advised to upgrade to these updated packages, which fix
these bugs.

Solution

Before applying this update, make sure all previously released errata relevant
to your system have been applied.
