This year, by way of an experiment we tried recording the audio through the sound system of the talks track and one Microconference track (Those in Platinum C). Unfortunately, because of technical problems, we have no recordings from Wednesday, but mostly complete ones from Thursday and Friday (Missing TPM Software Stack Status and Managing the Impact of Growing CPU Register State).
To find the audio, go to the full description of the talk or Microconference (click on the title) and scroll down to the bottom of the Abstract (just before the Tags section). The audio is downloadable mp3, so you can either stream directly to your browser or download for later offline listening.
If you find the audio useful (or not), please let us know (contact@linuxplumbersconf.org) so we can plan for doing it again next year.
