Just to check I understand the problem correctly. You have a system that has both analogue and digital mics connected, and the problem is that DMIC_ENA is then permanently enabled, meaning you can't access the audio from the analogue mics? Assuming I am correct above, looking through the DAPM graph it does look like the DMIC is oddly wired. It does appear to be hard wired into ADCL, which would indeed cause it to be permanently enabled if the pins are configured for DMIC. Assuming there isn't some reason the chip can't switch between digital and analogue modes (I can't see an obvious one in the datasheet), I think really there is a DAPM mux missing here. There should be a mux connecting both MIXINL and DMIC_ENA to ADCL/ADCR, rather than them both being directly connected that would let the user switch between analogue and digital inputs.

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? The input routing on this chip is pretty byzantine, the output of just "amixer" showing all the controls in the relevant use-case would probably be helpful to look over.

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. > > The input routing on this chip is pretty byzantine, the output of > just "amixer" showing all the controls in the relevant use-case > would probably be helpful to look over.

We can even make the mic available now (to enable manually by the user) while we look into the volume and detection. so long, all the best, martin [-- Attachment #2: amixer_contents.txt --] [-- Type: text/plain, Size: 19036 bytes --] numid=1,iface=CARD,name='Headphones Jack' ;

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?

I would suggest only using the PGA switch. Ok, I think what is happening here is you have both of these connected, and because you have the PGA muted, you are only hearing the unboosted mic signal coming through MIXINR IN3R. This would explain both why the Capture Volume has no effect and why your signal is quiet. Thanks, Charles ^ permalink raw reply [flat|nested] 16+ messages in thread

I keep MIXINR IN3R Switch disabled now and the volume is indeed high now, and I control volume using CaptureSwitch "name='Capture Volume'" Volume itself indeed is good now. Recorded voice is very "metallic" and "shallow" if you know what I mean - and distorted when using MAX volume. The gnome audio recorder doesn't show *any* signal in the UI, so that must still be kind of bad - even though I understand recorded voice way better now than before. > > Thanks, > Charles thanks for all the time and help, and sorry for all the wrong amixer output I sent you, martin [-- Attachment #2: amixer_contents_headset_20220207.txt --] [-- Type: text/plain, Size: 19034 bytes --] numid=1,iface=CARD,name='Headphones Jack' ;

You have a lot of the gaines up very high from when you were trying to working around the low signal level issues. Can we be clear here on what paths are in play here. Presumably the gnome audio recorder is capturing over the I2S. When you say you can understand the recorded voice way better now, do you mean in the file captured by the gnome audio recorder? Or are you listening to that on another path, like direct to the headphones? > thanks for all the time and help, and sorry for all the wrong amixer > output I sent you, > No problem, always a bit of back and forth in these debugging exercises. > numid=10,iface=MIXER,name='Capture Volume' > ; type=INTEGER,access=rw---R--,values=2,min=0,max=63,step=0 > : values=63,63 > | dBscale-min=-23.25dB,step=0.75dB,mute=0 This is +24dB, I would start with something like +0dB, +3dB or +6dB. > numid=7,iface=MIXER,name='MIXINR PGA Volume' > ; type=INTEGER,access=rw---R--,values=1,min=0,max=7,step=0 > : values=7 > | dBrange- > rangemin=0,,rangemax=1 > | dBscale-min=0.00dB,step=6.00dB,mute=0 > rangemin=2,,rangemax=2 > | dBscale-min=13.00dB,step=13.00dB,mute=0 > rangemin=3,,rangemax=4 > | dBscale-min=18.00dB,step=2.00dB,mute=0 > rangemin=5,,rangemax=5 > | dBscale-min=24.00dB,step=0.00dB,mute=0 > rangemin=6,,rangemax=7 > | dBscale-min=27.00dB,step=3.00dB,mute=0 > Hmm... step size here seems to disagree with the datasheet but this is either +29dB or +30dB depending on who we trust. So combining those two you have like +54dB of analogue gain, like no way that isn't causing the signal to clip. I would start with 0dB on each, then bump them up to like +6dB if the signal is really quiet. But somewhere you should be able to get specs on the mic and work out what actual gain you need to get a full scale signal out of the mic for the given micbias voltage. Your hardware folks should be able to help out there. Thanks, Charles ^ permalink raw reply [flat|nested] 16+ messages in thread

Sorry for not replying earlier. Mainly cset "name='MIXINR PGA Volume' 0,0" made things much better indeed. I took a break from this then and the issue is still open, here: https://source.puri.sm/Librem5/librem5-base/-/merge_requests/296 or if you want to look at the current ucm file: https://source.puri.sm/Librem5/librem5-base/-/blob/bb48912242dd0db1f35c6de8425984414c6d37bb/default/audio/ucm2/Librem_5/HiFi.conf As you know I'm no expert with the codec and this definitely can be improved: When visualizing the signal, it doesn't look "good" yet and the signal strength seems to only go to 50% of the available scale (in the gnome volume setting). Actually I'll talk about this to Guido tomorrow and even though it is kind of usable now, I hope to that we can come up with a profile that we're preliminarliy happy with. Of course we already use your "Input Mode" control. thanks, martin ^ permalink raw reply [flat|nested] 16+ messages in thread

That's a later amplifier, "Boost-Mixer Gain".

I think there are still maybe a couple things I am not sure on. I would try removing these two lines: cset "name='MIXINR IN3R Switch' on" cset "name='MIXINR IN3R Volume' 6" I am pretty sure we want to be using the PGA path here. If you check Figure 13 in the datasheet, you can route IN3R to MIXINR either through the IN3R input or through the PGA input. I suspect we want to come through the PGA. Using the IN3R path should mean the PGA volume has no effect, it is effectively bypassing the PGA. You may need to also add: cset "name='MIXINR PGA Switch' on" Although your previous control dumps had that input set on. I suspect if you have both enabled you will get some slightly weird effects, there is probably a slightly phase delay through the PGA and there won't be on the direct path, so when they mix together it will likely sound weird. Hopefully that gets us to a clean signal. The settings described in your commit message give +9dB analogue gain which seems reasonable to me, and from the patch itself looks like you have +15dB digital gain, which feels a little high but not total unreasonable.

I think we probably bump the PGA gain up another 3dB, maybe even 6dB if you really need to, I would just be careful to test some very loud sound levels to make sure your not starting to clip the signal.
