Thank you for your feedback.
I am having a look at the web server issue.
Assessing WeTeK issues without WeTek hardware will be very complicated for me
Thx. for your reply. Sure, I understand that this is complicated. Do you have any advice where I should start searching, i.e. log-files or tweaking some settings?
Here is a preview of release 104 of the addon for LE7 on WeTek Play.Please report if it makes or breaks.
Thanks for the update. Unfortunately, it breakes 
1) Kodi needs to use other audio in order to hear anything through the add-on
2) Sound still scratches
3) Port 4000 just shows "Loading..." (OK, that is not really an issue but still worth mentioning)
Do you need any logfiles or something?
I am building a preview version for LE7 on WeTek Play, and I will post it in my next reply.
Thanks, that's great to hear that! Happy to volunteer for testing 
BTopbas,I am afraid I can not do much, especially with the scarce information I have and without a WeTek Play to test. I will nevertheless have a look at alsa on LE, and see if there is anything I can improve. This might take a while, though.
Thank you for your patience
I have a Wetek Play myself, installed LE702 and the spotify addon. I can confirm, there is no spotify sound if Kodi uses the same audio device, and that the sound received via spotify (if Kodi is switched to another audio device) is scratchy.
If you let me know what exactly you would need to perform a deeper debugging, I am happy to help.
