There is no reason why the internal microphone or speakers cannot be used when a headset is plugged in.
The jack does not physically disconnect these, so the JackHWMute settings are wrong, remove them.
Are you sure about the internal mic and headset input not conflicting? IIRC they use the same path after the initial routing selector. I may be wrong but I'd be surprised if you can use both.
Now that I think of it further, in case the SSP0 is used an I2S link is configured, so you cannot have both streams in parallel. It may be possible to use headset and dmic in parallel with the 4 slot version but we also have 1 PCM capture only.
So overall it seems rather unlikely that we can support dmic + headset mic in parallel?
Right that is what the ConflictingDevices sections are for.
Removing the JackHWMute does not allow using both add the same time, it merely allows overriding which of the 2 to use (if the headset mic is detected by the jack, the JackControl setting is kept).
So lets say the internal mic is crappy, but the user prefers to have their ears free, then they can use a headset around there neck, using just the headset-mic and select speakers as output even though a jack is inserted.
Note pulseaudio will still automatically switch to the headphones / headsetmic when plugged in, this merely allows overriding that choice manually.
Jacks which actually physically disable (or re-route) signals are quite rare now a days so having a JackHWMute in the UCM conf is often wrong. After this patch only a few cases are left:
[hans@x1 alsa-ucm-conf]$ ack -l JackHWMute ucm2 ucm2/HDA-Intel/HiFi-dual.conf ucm2/chtrt5650/HiFi.conf ucm2/hda-dsp/HiFi.conf ucm2/codecs/es8316/HeadPhones.conf ucm2/sof-bdw-rt5677/HiFi.conf ucm2/broxton-rt298/HiFi.conf ucm2/skylake-rt286/HiFi.conf
The es8316 case is actually correct, the es8316 has only 1 output (which is amplified for e.g. a speaker) and at least the reference design suggests routing the speaker signal through the jack and using a jack which will interrupt the signal when headphones are plugged in.
Note most actual designs implement this with an analog switch and a GPIO to control that switch, since 3.5 mm jacks which actually can disconnect a signal are rare (if they exist at all, but I guess they do). For the designs using the GPIO controlled analog switch, the JackHWMute technically also is wrong, but I put it there (IIRC it was me) because it matches the reference design.
I'm not familiar enough with any of the others to say anything about them, but most of them are for HDA setups, where this is somewhat more normal I guess.
Regards,
Hans
