Patrakov <patrakov@gmail.com>"> Alexander E. Patrakov</a> <pre>So (without the log) I have a theory. When the monitor is DPMSed, its HDMI audio port becomes unavailable. PulseAudio notices that and, due to module-switch-on-port-available, switches. To verify the theory, please disable the module in /etc/pulse/default.pa, enable DPMS, and retest. It would be especially interesting (but I understand that it's a bit more than one can expect from a user) if you compiled PulseAudio from git, with this commit reverted, just to prove or disprove that it is indeed the curlpit: author David Henningsson <<a href="mailto:david.henningsson@canonical.com">david.henningsson@canonical.com</a>> 2015-11-17 14:10:35 (GMT) committer Tanu Kaskinen <<a href="mailto:tanuk@iki.fi">tanuk@iki.fi</a>> 2015-11-22 02:59:30 (GMT) commit e87100d41ef6d14f8dc7f803582191d9f8d8f183 (patch) tree 51caaca6a650c58a702fedb0a0228f7cf7775c23 parent 063a1d350fad1cb6fac28dbffe26a7e805626cb2 (diff) module-switch-on-port-available: Route to preferred profile This makes the routing slightly more aggressive: * It will try to route to another profile, if such a profile is preferred by the port. * It will allow changing profiles on transitions both to PA_AVAILABLE_YES and PA_AVAILABLE_NO To accommodate there is also some refactoring. Signed-off-by: David Henningsson <<a href="mailto:david.henningsson@canonical.com">david.henningsson@canonical.com</a>> There is also a patch on the mailing list that attempts to fix up the module for a different bug, but I suspect that it will not help: <a href="https://patchwork.freedesktop.org/patch/72053/">https://patchwork.freedesktop.org/patch/72053/</a></pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
