5 Audio Settings
5.1 Switching Audio Output Channel
To switch the audio output channel, go to "System Tools" -> "Qterminal"，enter the following command in the terminal to check available audio output channels:
export XDG_RUNTIME_DIR=/run/user/1000 pactl list sinks short
On the NanoPC-T6, the results appear as follows. The string beginning with alsa_output in the second column is the value we will use:
0 alsa_output.platform-dp0-sound.stereo-fallback module-alsa-card.c s16le 2ch 44100Hz SUSPENDED 1 alsa_output.platform-hdmi0-sound.stereo-fallback module-alsa-card.c s16le 2ch 48000Hz SUSPENDED 2 alsa_output.platform-hdmi1-sound.stereo-fallback module-alsa-card.c s16le 2ch 44100Hz SUSPENDED 3 alsa_output.platform-rt5616-sound.multichannel-output module-alsa-card.c s16le 2ch 44100Hz SUSPENDED
Use an editor to modify the PulseAudio configuration file:
sudo vim /etc/pulse/default.pa
If you need to set the audio output to HDMI1, replace the following line at the end of the file:
set-default-sink alsa_output.platform-hdmi0-sound.stereo-fallback
with:
set-default-sink alsa_output.platform-hdmi1-sound.stereo-fallback
Save the file and restart the system for the changes to take effect, or restart the PulseAudio service:
pulseaudio -k pulseaudio --start
5.2 Multi-Device Audio Output
Edit the PulseAudio configuration file:
sudo vim /etc/pulse/default.pa
Scroll to the end of the file, delete any line that starts with set-default-sink, and add the following lines at the end:
load-module module-combine-sink sink_name=combined slaves=alsa_output.platform-hdmi0-sound.stereo-fallback,alsa_output.platform-hdmi1-sound.stereo-fallback set-default-sink combined
Restart the system. With this configuration, audio will output simultaneously to both the HDMI0 and HDMI1 interfaces.
