Volume / sensitivity of Analog input is too low, I saw that before. What would you try to change that?
Hmm... you say you saw this before? I assume the input volume is always low, not just low sometimes? I would probably start by checking the voltage you have on the micbias, make sure that is as expected. Does the signal coming into the IN3R pin look low on a scope or is it just the level after it has been through the ADC on the chip that seems low?
Literally *no* effort went into this yet :) All I see is when I set the "headset mic" volume to max in gnome settings, the recorded volume is something like "almost usable", so that's off a bit.
I can't easily measure, but different headset mics produce similar volume.
No problem keep me posted any additional tests/info you guys get might help out here. Looking through your routing I think you are sending the mic directly to the speaker, I would definitely test capturing the signal over the I2S as well to confirm it is consistently a low volume on both paths.
:) thank you very much so far. You already really helped. We can even make the mic available now (to enable manually by the user) while we look into the volume and detection.
Happy to help, please feel free to keep the questions/debug info coming.
yes my bad :) If I may, just let me describe my situation again and see whether anything else comes to your mind.
It's weird but I when I set "Capture Volume" to 60 instead of 29, I didn't hear a difference.
So far I don't hear a difference when setting "INPGAR IN1R Switch" on.
Does "Value" in this ucm description make any sense to you?
EnableSequence [ cset "name='Digital Capture Volume' 127,127" cset "name='Capture Volume' 63,63" cset "name='MIXINR IN3R Switch' on" cset "name='MIXINR IN3R Volume' 7" cset "name='INPGAR IN1R Switch' on" cset "name='Input Mode' Analog" ]
DisableSequence [ cset "name='INPGAR IN1R Switch' off" cset "name='MIXINR IN3R Switch' off" cset "name='MIXINR IN3R Volume' 0" cset "name='Input Mode' Digital" ]
Value { CapturePriority "100" CaptureChannels "2" CaptureSwitch "name='MIXINR IN3R Volume'" CaptureSwitch "name='MIXINR IN3R Switch'" CapturePCM "hw:${CardId},0" JackControl "Headphones Jack" }
Let me just append the correct amixer contents where I hear my usual "quiet and bad signal" recording:
