I can "fix" this issue by pluging out the USB cable and plug it in again after waking my PC up from sleep mode. But doing this after EVERY time I put my PC into sleep mode is kind of tiring. Neither UCube nor Microsoft support were actually helpful on this...

Is there maybe a x-mas miracle that would solve this issue? Can I immitate the usb plug in/out via software?

  • Workaround: buy a USB hub with buttons that electronically let you disconnect/reconnect USB devices w/o wearing down USB ports – gregg Apr 16 at 15:04
  • @gregg Makes sense in general, however, pluging the cable out and in became such a habbit that I think will not be improved by a switch... – Cyman Apr 17 at 19:01

In the post No sound from session on login screen after sleep. Changed after 1809, the solution was to run as Administrator the following code:

sc stop Audiosrv
sc config Audiosrv obj= "NT AUTHORITY\LocalService" password= ""
sc start Audiosrv

If these commands when run in a Command Prompt (CMD) as Administrator, succeed in restoring the functioning of your device, then as a workaround you could paste them into a .bat file and use the Task Scheduler to create a new task with highest privileges to run at logon of any user and after sleep.

  • Thanks, this would have been an elegant solution. However, it doesn't work with my uCube speakers I'm afraid... – Cyman Apr 14 at 5:55
  • (1) Do the other speakers work after sleep? (2) Try Start > Troubleshooting > Troubleshoot audio playback. – harrymc Apr 14 at 8:53
  • When I enter the first command, I get an error message saying something like "A stop sign was sent to a service, which other services depend on" – Cyman Apr 14 at 19:27
  • Yes, other speakers work after sleep mode - however, the working speakers are powered directly (and not via USB like the uCubes) – Cyman Apr 14 at 19:29
  • The UCube device might have problems when powered down & up, so perhaps you should keep it from sleeping (or let it sleep if it doesn't now). Here are two helpful links: link1 and possibly also link2. – harrymc Apr 14 at 19:43
