Step 0. Power off or disconecct your Mytec Stereo 192.
INSTALL FIRMWARES (Outdated)
Install these two Snakeoil modules - fix kernel upgrade, and mytekusb2.fw.
Step 1. You need to install firmware 0.1.5-pre-release-20161216 or newer.
Step 2. Download the fix kernel upgrade file from this thread. Watch the video to get a quick idea on how to upload the file to your Snakeoil machine. The firmware upgrade looks like this and is available in the System tab. Make sure it report no errors.

Step 3. Download this module and again upload it to your Snakeoil.[attachment=86]

INSTALL CUSTOM MYTEK KERNEL
Step 4. Download this kernel. Upload it to your Snakeoil machine using the Vmzlinuz Upgrade option in the System tab (shown below). Again make sure there are no errors. [attachment=105]


Notes: Step 3 is necessary because I can't host the files here because of copyrights. What this module does is download the driver setup directly from Mytec and extract the 3 firmware files for you. Because the files are hosted on Mytec in time there is a chance this module will no longer work (OTOH maybe it's ok as this DAC is slated to be EOL in Winter 2016). Also I suspect the module in Step 5 will only work if your Mytec firmware is updated to v1.8.3. For other firmware versions refer to this document.
TROUBLESHOOTING
If you have trouble getting the Mytek USB2 device running, try and upload this firmware, then SSH into your snakeoil machine, and run the following (enter your user password when prompted):[attachment=94]
[s]sudo /usr/local/bin/mytekusb2-firmware-loader.sh[/s]
The following probably don't do anything, but you can try and see if this helps:
[s]sudo apt-get install alsa-firmware-loaders[/s]
