Alright, here’s what I’ve encountered with a Dell Venue 8 Pro 5855, a no-name type c dock with PD/LAN/USB3/HDMI and a SMSL SU-9 DAC connected to it.
Installation to the internal eMMC works perfectly. The internal sound card doesn’t seem to work. When I select it, it shows me a ton of hardware mixers but all of them produce an error message. Didn’t look into it further as I’m only using my DAC for music.
USB audio with the SMSL SU-9:
This works fine for the most of it but I did ran in to an issue with MQA encoded music from Tidal. There were random dropouts causing the DAC to switch back and forward from MQA to DSD. I believed this had to do with timing issues so I did some tinkering after which I came to the following conclusions:
- Adding “options snd-usb-audio autoclock=N” to the file /etc/modprobe.d/alsa-base.conf somewhat lessens the MQA playback problem but doesn’t solve it.
- Disabling “C-States” in the bios solves the issue with MQA playback completely regardless of the autoclock setting. This makes me think it has to do with the CPU (or bus speed) throttling during playback. This might be fixed with some kernel options or ACPI settings.
- The file /etc/modprobe.d/alsa-base.conf contains “options snd-usb-audio nrpacks=1” which is deprecated and ignored as the DMESG output will show.
Suggestion/feature request:
I’ve noticed that it shows a local GUI on the tablet that actually works with the touchscreen which is very cool! Unfortunately it won’t rotate the screen by itself. It would be nice to have a setting that allows the user to rotates the screen. Perhaps my guide might be of help on how to implement this: [GUIDE] Touch screen rotation on Volumio 3
