No sound output device recognized by PulseAudio

I'm setting up Ubuntu 18.10 one step at a time on my Jumper EZPad Mini 3, a cheap Chinese Windows tablet. Now I'm trying to get audio to work - just headphone jack output working is enough for me (no need for speakers).



The tablet uses a ES8316 codec, which the kernel seemingly already has support for, as its kernel module loads alright:



[    7.686752] bytcht_es8316 bytcht_es8316: snd-soc-dummy-dai <-> media-cpu-dai mapping ok
[ 7.686856] bytcht_es8316 bytcht_es8316: snd-soc-dummy-dai <-> deepbuffer-cpu-dai mapping ok
[ 7.689502] bytcht_es8316 bytcht_es8316: ES8316 HiFi <-> ssp2-port mapping ok


In its current state, the tablet lists only a Dummy Output in Settings. PulseAudio doesn't seem to see the card, listing only HDMI output (which I don't plan to use):

I've read a bunch of other answers and tried the usual restarting ALSA/PA, clearing/rebuilding PA config, even purging and reinstalling ALSA/PA, but nothing changed.



EDIT: I should also note that connecting Bluetooth headphones will result in PA seeing a new BT card, and also being able to output audio (albeit with heavy stutter, but that's outside the scope here). To me this means PA actually works alright, I just need to make it see the card somehow.



What can I do at this point?

    I'm setting up Ubuntu 18.10 one step at a time on my Jumper EZPad Mini 3, a cheap Chinese Windows tablet. Now I'm trying to get audio to work - just headphone jack output working is enough for me (no need for speakers).



    The tablet uses a ES8316 codec, which the kernel seemingly already has support for, as its kernel module loads alright:



    [    7.686752] bytcht_es8316 bytcht_es8316: snd-soc-dummy-dai <-> media-cpu-dai mapping ok
    [ 7.686856] bytcht_es8316 bytcht_es8316: snd-soc-dummy-dai <-> deepbuffer-cpu-dai mapping ok
    [ 7.689502] bytcht_es8316 bytcht_es8316: ES8316 HiFi <-> ssp2-port mapping ok


    In its current state, the tablet lists only a Dummy Output in Settings. PulseAudio doesn't seem to see the card, listing only HDMI output (which I don't plan to use):

    However, ALSA seems to acknowledge the card just fine:

    But then again, if I try to manually assign a card to play a wav file, aplay errors out:

    I've read a bunch of other answers and tried the usual restarting ALSA/PA, clearing/rebuilding PA config, even purging and reinstalling ALSA/PA, but nothing changed.



    EDIT: I should also note that connecting Bluetooth headphones will result in PA seeing a new BT card, and also being able to output audio (albeit with heavy stutter, but that's outside the scope here). To me this means PA actually works alright, I just need to make it see the card somehow.



    What can I do at this point?

      I'm setting up Ubuntu 18.10 one step at a time on my Jumper EZPad Mini 3, a cheap Chinese Windows tablet. Now I'm trying to get audio to work - just headphone jack output working is enough for me (no need for speakers).



      The tablet uses a ES8316 codec, which the kernel seemingly already has support for, as its kernel module loads alright:



      [    7.686752] bytcht_es8316 bytcht_es8316: snd-soc-dummy-dai <-> media-cpu-dai mapping ok
      [ 7.686856] bytcht_es8316 bytcht_es8316: snd-soc-dummy-dai <-> deepbuffer-cpu-dai mapping ok
      [ 7.689502] bytcht_es8316 bytcht_es8316: ES8316 HiFi <-> ssp2-port mapping ok


      In its current state, the tablet lists only a Dummy Output in Settings. PulseAudio doesn't seem to see the card, listing only HDMI output (which I don't plan to use):

      However, ALSA seems to acknowledge the card just fine:

      But then again, if I try to manually assign a card to play a wav file, aplay errors out:

      I've read a bunch of other answers and tried the usual restarting ALSA/PA, clearing/rebuilding PA config, even purging and reinstalling ALSA/PA, but nothing changed.



      EDIT: I should also note that connecting Bluetooth headphones will result in PA seeing a new BT card, and also being able to output audio (albeit with heavy stutter, but that's outside the scope here). To me this means PA actually works alright, I just need to make it see the card somehow.



      What can I do at this point?

      I'm setting up Ubuntu 18.10 one step at a time on my Jumper EZPad Mini 3, a cheap Chinese Windows tablet. Now I'm trying to get audio to work - just headphone jack output working is enough for me (no need for speakers).



      The tablet uses a ES8316 codec, which the kernel seemingly already has support for, as its kernel module loads alright:



      [    7.686752] bytcht_es8316 bytcht_es8316: snd-soc-dummy-dai <-> media-cpu-dai mapping ok
      [ 7.686856] bytcht_es8316 bytcht_es8316: snd-soc-dummy-dai <-> deepbuffer-cpu-dai mapping ok
      [ 7.689502] bytcht_es8316 bytcht_es8316: ES8316 HiFi <-> ssp2-port mapping ok


      In its current state, the tablet lists only a Dummy Output in Settings. PulseAudio doesn't seem to see the card, listing only HDMI output (which I don't plan to use):

      I've read a bunch of other answers and tried the usual restarting ALSA/PA, clearing/rebuilding PA config, even purging and reinstalling ALSA/PA, but nothing changed.



      EDIT: I should also note that connecting Bluetooth headphones will result in PA seeing a new BT card, and also being able to output audio (albeit with heavy stutter, but that's outside the scope here). To me this means PA actually works alright, I just need to make it see the card somehow.



      What can I do at this point?
