First of all, thank you for the support and for the suggestions. Wanted to provide some feedback and maybe help out someone else having similar issue. I had audio stutter when streaming radio, using tidal/spotify or playing local tracks. I did not find errors with the above commands, but it is definitely related to the quality of the Bluetooth signal (or better to say not the strongest bluetooth transmitter). Although it is below 10m distance from the bluetooth receiver, I've moved RPI4 closer and stutter was mostly gone (so thanks about that tip Paul). After that I've bought an external dongle (first one I've found in nearby store, it was gembird bt500 mini bluetooth 4.0 dongle). But I was not successful in getting this to work, as it turned out cambridge silicon radio chip used in this usb dongle is a fake chinese copy. I've tried to patch the OS, but was unsuccessful as this is beyond my knowledge of linux. Anyway, I've managed to return this one to the store and bought a new one (TP-link UB400 nano) and I can confirm this one works out of the box. So anyone having issues with RPI4 bluetooth and needs a small low power dongle, this one is working (you cannot believe how hard is to find online info which one is working good). That being said, stutter is almost all gone. I still have stutter when streaming radio stations (I'm trying to figure out what is the cause, because it is not the same with all stations), but tidal and spotify are working fine. So if someone is having bluetooth issues, 99% it is related to the bluetooth quality....as everything is working as expected. ------------------------------------------------------------------------ denmla's Profile: http://forums.slimdevices.com/member.php?userid=72559 View this thread: http://forums.slimdevices.com/showthread.php?t=114828 _______________________________________________ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix
