PulseAudio 4.0 and Skype

This is a public service announcement for packagers and users of Skype and PulseAudio 4.0. In PulseAudio 4.0, we added some code to allow us to deal with automatic latency adjustment more gracefully, particularly for latency requests under ~80 ms. This exposed a bug in Skype that breaks audio in interesting ways (no sound, choppy […]

Yay, we just released PulseAudio 3.0! I’m not going to rehash the changelog that you can find in the release announcement as well as the longer release notes. I would like to thank the 36 contributors over the last 6 months who have made this release what it is and continue to demonstrate what a […]

grsec and PulseAudio (and Gentoo)

This problem seems to bite some of our hardened users a couple of times a year, so thought I’d blog about it. If you are using grsec and PulseAudio, you must not enable CONFIG_GRKERNSEC_SYSFS_RESTRICT in your kernel, else autodetection of your cards will fail. PulseAudio’s module-udev-detect needs to access /sys to discover what cards are […]

Gentoo: PulseAudio + ALSA update

For a long time now, fellow-Gentoo’ers have had to edit /etc/asound.conf or ~/.asoundrc to make programs that talk directly to ALSA go through PulseAudio. Most other distributions ship configuration that automatically probes to see if PulseAudio is running and use that if avaialble, else fall back to the actual hardware. We did that too, but […]

PulseAudio 1.1 (the echo release?)

Yep, if we keep this up, it could even become a habit! PulseAudio 1.1 is out. It’s mostly a bunch of bug fixes on top of 1.0. Most important of these are fixes for: a libpulse dependency on libsamplerate (if enabled) which would make our LGPL license invalid, broken Skype audio capture (because we changed […]

Alternate sample rates

I’ve just pushed a bunch of patches by Pierre-Louis Bossart that can have a pretty decent CPU/power impact. These introduce the concept of an “alternate sample rate”. Currently, PulseAudio runs all your devices at a default sample rate, which is set to 44.1 kHz on most systems (this can be configured). All streams running at […]

As Colin Guthrie reports, PulseAudio 1.0 is now out the door! There’s a lot of new things in the release, and we should be getting a much more regular release schedule going. Head over to the full release notes for more details. A lot of people have contributed to this release and thanks to them […]

Well done, Adobe!

In an unsurprising turn of events, Adobe completely fails to play well with modern Linux systems. Well done, guys. Well done, indeed. p.s.: I was quite happy to see that the Google Talk plugin has proper PulseAudio support (thanks to the WebRTC née GIPS code, it looks like).

Desktop Summit 2011

I’m in Berlin at the Desktop Summit, so you can drop me a note and we can meet if you want to yell about PulseAudio things that annoy you (or even, y’know, things you like).
