Thanks for the link. Edited to the default configuration. I will be
repeating the diagnostic steps requested in comment #1 and post the
updated output.
Little apparent change so far. Audio output still works as expected.
Microphone still not working, neither the internal one nor the one in
the headset. Instead of continuous high pitch sound, the headset emits
a low frequency pulsating sound.
> do your Sony support headset (headphone with Mic) instead of headphone
?
Yes.
I am trying to make sense of the log excerpt in comment #11.
What is a "Phantom Jack"?
I would be tempted to guess that the log means:
- speaker found
- no headphone found
- two microphones found, one on the Mic Jack (logged twice) and one on the
Internal Mic Phantom Jack
AFAIK the SONY has two microphones onboard. Is it possible that one of
them is wired to the Mic Jack and the other one to the Internal Mic
Phantom Jack? And that the headset would be a third microphone?
When I run pavucontrol, I see two mics: Microphone and Internal
Microphone. Connecting the headset does not add a third microphone.
I have a bluetooth headset (BTH) too. I have kept it off this report to
focus on the basic microphone. I have spurious problems with the BTH
too. But maybe this information about the BTH can help diagnose my
problems.
~/.asoundrc:
pcm.btheadset {
type bluetooth
device XX:XX:XX:XX:XX:XX
profile “auto”
}
When I connect the BTH, it shows up in pavucontrol, unlike the wired
headset. However it is spurious:
Start from all devices off:
* Boot laptop
* Turn BTH on and it shows in pavucontrol
* Turn BTH off and it disappears in pavucontrol, as expected
* Turn BTH on again and it does not show in pavucontrol, against expectation
Start again from all devices off:
* Turn BTH on
* Boot laptop
* BTH does not show in pavucontrol, against expectation
* Turn BTH off and on again, tt does not show in pavucontrol, against
expectation
Also, when the BTH is listed in pavucontrol, it does not work. Skype is
muted when it would be expected to play and record to/from the BTH.
On the bluetooth end, I cannot connect to the audio sink (Stream setup
failed). I recall that I was able to play music using VLC only once,
after which I lost the functionality and did not care too much because I
was not really using it.
I hope this does not make my report more confusing.
