Low Volume on Revolve Soundlink & Soundlink Micro
I have a TROND as well as a Aluratek bluetooth transmitter device. I use the aux outlet on a tv and plug it into these bluetooth transmitters to project sound from the tv to my bose speakers while using a hot tub. When I originally got the Revolve Soundlink - it was great I could watch tv using bluetooth to my revolve speaker and no problem. A few months back my bose Revolve got a firmware update and the sound now plays at like 50% volume and isn't loud enough to use now. I have tried 3 different bluetooth transmitters and none of them now work with my Revolve speaker to a volume level that is adequate. I also bought a Bose Micro Soundlink and I have this same issue. I can use other bluetooth speakers like an Alexa portable speaker with my bluetooth transmitters on the tv but not the bose products. This is annoying becasue I have the one fully waterproof speaker and the revolve that is water resistant yet I have to use an Alexa speaker for sound.
Is there anyway to fix this? I have removed and re-added the speaker multiple times. I have checked the volume in the app, nothing seems to be able to make the speaker loud enough to use. With my cell phone or other bluetooth devices it is fine, but it appears there is something that happened in the latest firmware that made these speakers unusable.
