Receiver speaker not working

@luisjoly Have you checked out the CSD tool's (https://together.jolla.com/question/56805/no-sound-from-notifications/?answer=56815#post-id-56815) microphone tests Audio below microphone and Audio above microphone under Individual tests? Could you playback your recording?

Almost everything worked perfectly. Except for the receiver playback. I didn't hear anything. Anything I could do here?

Having thought some minutes more about your description again and about your CDS test result it looks to me like an issue with the receiver speaker/"ear speaker". The speaker is connected by means of spring contacts like the loudspeaker and may be you're encountering an contact issue.

You could find some images of the loudspeaker in No sound through speaker. I encountered the same issue some months ago and could solve it temporarily by squeezing the phone and a "spring-cleaning".

Because you could make phone calls in hands-free mode I would not blame the microphones. What happens when you talk to someone with the phone on your ear? Could he hear you? The CSD tests for the microphones seem to playback via the loudspeaker and therefor i its hard to say whether there is something wrong with the microphones or the receiver just from these tests.

@strongm had success with running sequence of CSD tests and restarting pulseaudio. But the resolution might originate from a mechanical stimulus while working with the device. Did you restart your device and test it with a freshly started pulsaudio?

@lechris Yesterday I ran the CSD tools once again. Something curious happened. I tested the receiver WITH the headset on, on purpose, and then removed it shortly after the test began. Then, the sound appeared! But it didnt solve anything, the problem persists. Regarding the question about what happened when the phone is on my ear - I can't hear absolutely anything (malfunction) and the screen blocks (as it should). The CDS tools shows there is no problem with proximity sensor as well. But the person on the other line CAN hear me perfectly. And here's the main question, @strongm: how do I restart pulseaudio?

@luisjoly To me it currently looks like a contact issue with the receiver speaker or pulseaudio. May be you squeezed the phone while unplugging the headphone jack a teensy bit ... Could you describe how the problem persists more in detail? When did it stop? What did you do when you noticed it failed again?

I'm sorry that I have any Idea how to deal with pulsaudio except rebooting. Did you give it a try?

From my point of view we've sorted out the microphone. Could you please update the title to something like Receiver speaker not working?
