Audio output device forced to Default, Bluetooth Audio (PULSEAUDIO)

    I don't have any audio through my HDMI anymore after I upgraded to the latest version (8.2.3). I lost the option to change the audio output device (it's set to Bluetooth audio which I think may not even be supported by my miniPC). Also, the passthrough settings section is completely empty. Setting the number of channels to 2 (and many other setting combinations) does not change this.

    I found that some people have this issue with NVIDIA chipsets (which I have as well) that it defaults to bluetooth due to a bug.

    I tried following the steps of the only workaround I could find for this issue: PulseAudio/Examples - ArchWiki

    When I do

    aplay -l

    I get:

    **** List of PLAYBACK Hardware Devices ****

    card 0: NVidia [HDA NVidia], device 0: ALC662 rev1 Analog [ALC662 rev1 Analog]

    Subdevices: 1/1

    Subdevice #0: subdevice #0

    card 0: NVidia [HDA NVidia], device 1: ALC662 rev1 Digital [ALC662 rev1 Digital]

    Subdevices: 1/1

    Subdevice #0: subdevice #0

    card 0: NVidia [HDA NVidia], device 3: HDMI 0 [HDMI 0]

    Subdevices: 1/1

    Subdevice #0: subdevice #0

    Following the guide I test if my HDMI still works:

    aplay -D plughw:1,3 ~/downloads/sample.wav

    Yay, the sound works! So far so good.

    I proceed with:

    load-module module-alsa-sink device=hw:0,3

    I get a return code:

    16

    Not sure if this is a problem or not.

    I continue with:

    pulseaudio -k

    result:

    E: [pulseaudio] main.c: Failed to kill daemon: No such process

    ehhh.. is this normal? Maybe it was already shut down or never even running?

    I try to start it:

    pulseaudio --start

    result:

    W: [pulseaudio] main.c: This program is not intended to be run as root (unless --system is specified).

    The settings stay the same in kodi :(

    I tried another solution: editing /etc/pulse/default.pa

    Can't be done. This directory seems restricted from editing / adding / renaming files altogether. Even for root (?)

    Following daemon.conf.d brings me to a directory (~/.config/pulse-daemon.conf.d) where a README file explains I can create config files that would overwrite settings.

    I create hdmi.conf (with access rights to 777).

    #!/usr/bin/pulseaudio -nF

    load-module module-alsa-sink device=hw:0,3

    reboot

    No change. :@

    I must be missing something awfully fundamental as not many people seem to have this issue?
