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.
