7.0.3.010 (2016-12-09)
Player "Mini M8S TV Box 2GB 8GB Amlogic S905".
Connecting to an external USB DAC:
The DACs on the USB-receivers Texas Instruments TAS1020B, Savitech SA9023, Tenor TL7022L - Norm. Plays great!
The DACs on the USB-receivers XMOS 8U6C5 - Periodic crackling, Strong distortion.
Ок. I don't need more to do a log file?
I don't know. I don't have that kind of hardware and IIRC you haven't posted any logs so that I could tell whether it's a driver issue.
I posted logs in the first post. LibreELEC
I am a beginner and could be wrong. Tomorrow I'll do the logs again and post.
New development build to test:
LibreELEC-S905.aarch64-7.0-devel-20161202213923-r23473-g8a53869.img.gz

The DACs on the receivers XMOS 8U6C5 - Periodic crackling, Strong distortion.
Got to test the new USB-DAC on the usb receiver "Tenor TL7022L".
Tested "Build 7.0.2.009" and "Devel r23473" - Norm. Plays great!
Do I understand correctly that the USB-DACs on XMOS will not work on Libreelec?
A new build to test a/v sync, please: LibreELEC-S905.aarch64-7.0-devel-20161129232917-r23467-gdee7939.img.gz

Hi!
Player "Mini M8S TV Box 2GB 8GB Amlogic S905".
I have tested your all firmware. Test only sound output SPDIF (optical) and USB, only "Stereo", only 44/16 and Hi-res 96/24.
I have a lot of DAC's - 7 pieces. On different chips. Four DAC's - USB receiver TAS1020B and USB receiver SA9023.
Three DAC on the USB receiver XMOS 8U6C5.
So as I have the ability to test the optical output on the "Bitperfect".
It works like this: the Output on optics in the playback wav file -> (card with optical input) recording to wav file, and bitwise compare the original file and recorded file.
If you would be interested.
All builds output via optical frequency 44-192, with the bit depth from 16 to 24.
Check for Bitperfect.
Build 7.0.2.001 - 006:
44/16 - Bitperfect.
96/24 - Not Bitperfect.
Build 7.0.2.007 - 009:
44/16 - Bitperfect.
96/24 - Bitperfect.
Therefore, the optical output works fine!
Output sound via USB (ALSA-SPDIF)
Build 7.0.2.001 - 006:
The DACs on the receivers TAS1020B and SA9023 - Periodic crackling, small distortion.
The DACs on the receivers XMOS 8U6C5 - Periodic crackling, Strong distortion.
Build 7.0.2.007 - 009:
The DACs on the receivers TAS1020B and SA9023 - Norm. Plays great!
The DACs on the receivers XMOS 8U6C5 - Periodic crackling, Strong distortion.
All three on XMOS DAC work perfectly under Windows (XP, 7, 
and Linux Mint.

Can be for XMOS need to add drivers? Enable USB drivers on Linux
I don't know how to do it. Ready to continue testing.
log files from two XMOS devices attached. Performed "on" and play ape file to 44/16.
