Package: pulseaudio Version: 0.9.21-3+squeeze1 Severity: normal
I found that pa_stream_write with an offset that's not a multiple of the base sample size causes pulseaudio to assert and abort. This is not the case for the nbytes parameter of how many bytes to write, that is allowed to not be a multiple of the sample size, but the seek offset parameter must be a multiple of the sample size or it asserts. E: memblockq.c: Assertion 'length % bq->base == 0' failed at pulsecore/memblockq.c:519, function pa_memblockq_drop(). Aborting. Aborted pulseaudio 1.0-4 gives the following, E: [alsa-sink] memblockq.c: Assertion 'length % bq->base == 0' failed at pulsecore/memblockq.c:600, function pa_memblockq_drop(). Aborting. I've fixed the program causing it, I just wanted to make others aware that any program that can play audio can take down the audio daemon. -- System Information: Debian Release: 6.0.3 APT prefers stable APT policy: (500, 'stable') Architecture: i386 (x86_64) Kernel: Linux 3.2.0-rc5+ (SMP w/4 CPU cores) Locale: LANG=C, LC_CTYPE=en_US.ISO-8859-15 (charmap=ISO-8859-15) Shell: /bin/sh linked to /bin/dash Versions of packages pulseaudio depends on: ii adduser 3.112+nmu2 add and remove users and groups ii consolekit 0.4.1-4 framework for defining and trackin ii libasound2 1.0.23-2.1 shared library for ALSA applicatio ii libc6 2.11.2-10 Embedded GNU C Library: Shared lib ii libcap2 1:2.19-3 support for getting/setting POSIX. ii libdbus-1-3 1.2.24-4+squeeze1 simple interprocess messaging syst ii libgdbm3 1.8.3-9 GNU dbm database routines (runtime ii libice6 2:1.0.6-2 X11 Inter-Client Exchange library ii libltdl7 2.2.6b-2 A system independent dlopen wrappe ii libpulse0 0.9.21-3+squeeze1 PulseAudio client libraries ii libsamplerate0 0.1.7-3 Audio sample rate conversion libra ii libsm6 2:1.1.1-1 X11 Session Management library ii libsndfile1 1.0.21-3+squeeze1 Library for reading/writing audio ii libspeexdsp1 1.2~rc1-1 The Speex extended runtime library ii libudev0 164-3 libudev shared library ii libx11-6 2:1.3.3-4 X11 client-side library ii libxtst6 2:1.1.0-3 X11 Testing -- Record extension li ii lsb-base 3.2-23.2squeeze1 Linux Standard Base 3.2 init scrip ii udev 164-3 /dev/ and hotplug management daemo Versions of packages pulseaudio recommends: pn gstreamer0.10-pulseaudio <none> (no description available) pn libasound2-plugins <none> (no description available) pn pulseaudio-esound-compat <none> (no description available) pn pulseaudio-module-x11 <none> (no description available) Versions of packages pulseaudio suggests: pn paman <none> (no description available) pn paprefs <none> (no description available) ii pavucontrol 0.9.9-1 PulseAudio Volume Control pn pavumeter <none> (no description available) ii pulseaudio-utils 0.9.21-3+squeeze1 Command line tools for the PulseAu -- no debconf information -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
