Bluetooth Audio suddenly not working (pi3+)

1st Official Post

    Been using Bluetooth Audio Device Changer add-on to be able to stream music from my Android phone to Kodi on my pi3+ for a month now. When I wanted to play some music today it wouldn't play anything, and when checking the logs it seems like something has happened, but I can't really figure out how to solve it. I've tried rebooting Kodi, power cycling by pulling out power cable, however, no luck so far. Also tried disabling and re-enablig bluetooth + uninstalling and reinstalling (also tried both versions available in the add-on repo) the Bluetooth Audio Device Changer add-on, but nothing. When I try to enable the addon I get an message about an error and that I should check the log file for more details.

    I've uploaded some of the log files to pastebin:
    /storage/.kodi/temp/kodi.log:

    If anyone has any input that can help me solve this it'd be great. If other log files are needed, let me know.

    A couple of things for now, IMO:

    - If a totally fresh install of 8.2.5 only (no other addons) doesn't get BT audio to work, it could be a hardware problem.

    - Did the Bluetooth Audio Device Changer add-on recently get an update? It might have a bug, seeing the kodi.log entries. Contact its developer(s).

    - LE 8 = EOL, and will itself not get any more updates

    - Try LE 9 Alpha 3 for more results.

    Thanks for the feedback: Tried upgrading to LE 9 Alpha 3 now (including the corresponding version of the add-on for LE 9), but no luck.

    Also tried to remove add-on, reset all BT related settings in system menu (including pairing with phone again). Pairing seemed to work fine, so it seems to me that the BT part actually works as it should. Can try to set an upload folder and see if I can send files to the pi3+ though.

    New log (seems to be the same errors as yesterday):

    Will try to do a fresh install later today, hopefully I'll figure it out before it comes to that though.

    Noticed one thing now; in the settings for the Bluetooth Audio Device Changer the audio device is set to iec958:CARD=sndallodigione,DEV=0, in e.g. librespot it shows default:CARD=sndallodigione, could this related to the problem?

    Tried a fresh install now, but still doesn't work. Basically, everything else here works; the Alle DigiOne works just fine, audio is as expected both when playing video and music through e.g. librespot. Bluetooth works fine for transferring files, etc, so can't be that either. For me it boils down to that there must be something wrong with how the plugin works.

    As mentioned in my previous post there are little to no information about what/how the output device in the config of the add-on should be listed. If one select the default settings, it wipes whatever is in the Audio device field. Since this add-on is a Team LibreELEC add-on I assume someone in the developer team is the right person to contact here? Would be nice if the add-on listed the possible options of output devices like e.g. the librespot add-on does, in that way you at least know in which format it should be presented. At the moment I can't tell if it's not working because 1) I have specified the output device in the wrong format (see my previous post), or if it's because there are some flaws with the add-on itself.

    Also, this should maybe be placed in add-on support subforum, sorry for posting in the wrong subforum to begin with.

    Did a new fresh install and installed only the Bluetooth Audio Changer device. When Kodi is running I don't get any audio output at all, but if I ssh into the device and run systemctl stop kodi and pactl load-module module-udev-detect I suddenly can start streaming music again from my Android phone.

    So I can at least confirm that streaming works, it's not a HW related problem, and thus I just have to assume it's something that's become broken in either LibreELEC or the add-on itself with an update at some point.

    Code
    LibreELEC:~ # pactl list short sinks
    1       alsa_output.0.iec958-stereo     module-alsa-card.c      s16le 2ch 44100Hz       RUNNING
LibreELEC:~ # pactl list short sources
4       alsa_output.0.iec958-stereo.monitor     module-alsa-card.c      s16le 2ch 44100Hz       IDLE
5       alsa_input.0.iec958-stereo      module-alsa-card.c      s16le 2ch 44100Hz       SUSPENDED
7       librespot_sink.monitor  module-null-sink.c      s16le 2ch 44100Hz       SUSPENDED
12      bluez_source.14_9F_3C_81_30_CC.a2dp_source      module-bluez5-device.c  s16le 2ch 44100Hz       RUNNING

    It'd be great if someone from the developer team could look into this.
