Raymond tends to be side-tracked from time to time and ask questions which are related to your original issue. Also apologies for not having read the entire thread through.
PulseAudio closes the audio stream five seconds after no applications are active, so that's probably when the issue goes back to normal too. The resampler changed from "null" to "copy" means that we have a resampler engine active for the stream, but all it does is to convert from s16le (as being input by Chrome) to s32le. You're probably hitting a driver issue, but I wonder how we can prove it. Also the fact that it seems to hit one application only is a bit strange, maybe it's related to the requested latency by that specific application or something. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1315212 Title: [CA0106 - CA0106, playback] Playback problem - Surround dies, no valid output To manage notifications about this bug go to: https://bugs.launchpad.net/alsa-driver/+bug/1315212/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
