I am trying to get audio output onto HDMI and a Bluetooth box working simultanously.
This wiki entry suggests that this should be possible with the pulseaudio module-combine-sink
Unfortunately, I have a hard time to find my audio sinks. The sinks I am interested in are listed by Kodi as:
But neither pactl nor amixer shows me those two devices:
kodi-rpi4:~ # pactl list short sinks 4 auto_null module-null-sink.c s16le 2ch 44100Hz SUSPENDED kodi-rpi4:~ # pactl info Server String: /var/run/pulse/native Library Protocol Version: 34 Server Protocol Version: 34 Is Local: yes Client Index: 33 Tile Size: 65496 User Name: root Host Name: kodi-rpi4 Server Name: pulseaudio Server Version: 14.2 Default Sample Specification: s16le 2ch 44100Hz Default Channel Map: front-left,front-right Default Sink: auto_null Default Source: auto_null.monitor Cookie: 6087:a029 kodi-rpi4:~ # aplay -l **** List of PLAYBACK Hardware Devices **** card 0: vc4hdmi0 [vc4-hdmi-0], device 0: MAI PCM i2s-hifi-0 [MAI PCM i2s-hifi-0] Subdevices: 0/1 Subdevice #0: subdevice #0 card 1: vc4hdmi1 [vc4-hdmi-1], device 0: MAI PCM i2s-hifi-0 [MAI PCM i2s-hifi-0] Subdevices: 1/1 Subdevice #0: subdevice #0
In addition, I get:
Nevertheless, after executing
a new device appears in Kodi, called
When I select this device, my Bluetooth box plays fine. So the module-combine-sink basically seems to work. But how do I find the name of the HDMI sink so that I can add it to the combined sink?
What's more, all those settings don't change when I change outputs in Kodi.
https://kodi.wiki/view/PulseAudio says, it is not possible to have ALSA and Pulseaudio at the same time. But Kodi shows me ALSA devices as well as Pulseaudio devices. Can anybody elaborate on this? What is installed by default in a libreelec install on RPi 4B?
Thanks in Advance!
