So contacting Sonos about this issue, they redirected me back to the TRNTBL Vendor for Tech Support because the Sonos Connect Im working with was working in every other way (Except for seeing the TRNTBL when I selected the "Line-In" source on the Sonos App/ Software. With limited help with TRNTBL tech support (which is very basic and does not seem to know their own product very well or are not good at communicating clearly), I was able to figure out for myself how this works. If you are one of the lucky ones to just get past the TRNTBL Setup deal, This is how Im finding it to work.
If you are playing the TRNTBL and want change to Pandora or another streaming source.
- Stop the TRNTBL by lifting the needle and switching it OFF.
- Select the Steaming source and content to listen too
- When you want to play a record again, Turn the TRNTBL ON and drop the needle. The Sonos system will automatically switch to the TRNTBL source. THERE IS NO NEED TO SELECT THE "LINE-IN" SOURCE
I dont understand why these simple instructions are not known by Sonos or TRNTBL. Good luck. Hopefully TRNTBL can make a more intuitive app, Tech Support Dept, and reliable product.
