Installed the latest eaon image of http://cdimage.ubuntu.com/ubuntu /daily-live/current/ to the lenovo p520, and upgrade the pulseaudio to 1:12.2-2ubuntu4, Then I tested the recording and palyback, it worked as expected:
recording: plug a mic into the front audio jack, and select it from sound-setting, use arecord to record sound, after recording, unplug the front mic and plug it to rear mic, use arecord to record sound again, it still can record sound. playback: plug a headphone to rear lineout and select lineout as output device, then play sound via totem, after a while, close the totem and unplug the rear lineout and plug the headphone to front headphone jack, use totem to play sound, I can hear the sound from front headphone. It proves after applying the patch, both playback and recording works as expected. Please push the debdiff to disco. thx. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1834138 Title: PA: Don't restore the streams to sinks/sources with only unavailable ports Status in HWE Next: New Status in pulseaudio package in Ubuntu: Fix Released Bug description: SRU Document: [Impact] The Lenovo P520 machine has dual analogue codecs, so there are two sinks and two sources in the PA, one has the front headphone and front microphone, the other has the rear lineout, linein and rear microphone, and the rear microphone always shows up in the gnome- sound-setting, When we plug a microphone to front audio jack, there are two input devices: rear mic and front mic in the gnome-sound- setting, and suppose users select the the front mic to record sound via audio app like arecord, the front mic will be bond the arecord, after the front mic is unplugged, there is only one rear mic left in the gnome-sound-setting, but the binding will not be changed, the arecrod still bind to front mic, under this situation if users record sound via arecord, they will find they can't record any sound from any other input devices even they are listed in the gnome-sound-setting. This problem also happens to output devices too. [Test Case] After applying this patch, I did the same test: unplug the front mic, then use the arecord to record sound, the app can record sound from rear mic now. After I plug the front mic back, the arecord still record from front mic. Also did the similar test for output devices, it worked as expected too. [Regression Potential] No, Just make a simple check when creating new streams (sink_input/source_output), If the restored device (sink/source) has ports and all ports are unavialble, it will not restore the binding, otherwise it will work as before.
