I tried more than 2 output channels already. When I set the number of output channels to 4 or 8 on the (1st option) "USB Audio" I get in the console "ALSA: set output channels to 2". When I set the number of output channels to 4 or 8 on the (2nd option) " rockchip.miniarm-codec " I get no error in the console but also still no sound.

I wonder where the VLC player is getting ist output list from.
most likely pulse audio.
maybe the audio device has multiple output channels (and the two headphone channels are not the first two). try running Pd with more (8) channels.

Subject: [PD] Pd / Purr-Data and Ausus Tinkerboard - analog sound card does
not show up (alsa)
I'm testing the Asus Tinker Board at the moment but I cannot get Pd (0.46.2) or Purr-Data to talk to the internal sound card of the tinker board. It simply does not show up, neither as a normal user nor as root. I'm on Tinker-OS 1.4 which is the latest version as of now.
In the Purr-Data preferences I can see these available (alsa audio) options:
- USB Audio (hardware)
- USB Audio (plug-in)
- rockchip.miniarm-codec (hardware)
- rockchip.miniarm-codec (plug-in)
The rockchip.miniarm-codec gives me sound on my HDMI monitor but no sound from the regular analog audio out.
When I open the VLC player I get this for the audio devices:
- BT_HFP-Output
- SPDIF-Output
- Headset-Output
- rockchip.miniarm-codec Analog Stereo
- USB Audio Analog Stereo
Option 3 (the Headset-Output) gives me sound from the analog audio out connector as expected. Unfortunately this option does not show up in purr-data.
Has anybody else tried this board? Any ideas how to get sound from the normal audio out? After testing with Purr-Data only I just installed Pd 0.46.2 but I get the same options and no sound from the audio out jack.
Thanks for your feedback! Ingo
