I have the same issue when I play sound from an iPad by Bluetooth. On the Android device, it works correctly. Hardware:
Having the same problem here!
Hi, having opposite issue: volume always starts at 0%...
Different BT clients behave differently when it comes to BT volume control. As long as this isn't addressed for all systems correctly in blue-alsa, we can't do nothing. However, I would not recommend BT at al with an iPhone. Airplay is the much better and more stable choice for streaming music from an iPhone
I have the same problem here. It seems the volume gets set to 100% when I press play in the Spotify App on iPhone. I also noticed turning down the volume with a rotary control wired to the Raspi does lower the volume but does not effect the volume control bar on the iPhone.
I may have found a fix for some people that are facing this problem with a similar setup (Raspi, Amp, BT Dongle). It seems this is not directly a bug with HifiberryOS, i tested a few different BT Dongles and the bug does not occur on some.
Not working BT Dongles(LogiLink BT015, aplic USB BT nano V4.0) -> 100% Volume bug occurs
Working BT Dongles(Yizhet USB nano BT V4.0) -> 100% Volume bug does not occur
is there a list with dongles that work?
@dieterch, thanks for the good description of the problem. For me she was very helpful. @leonka10, the reference to the Bluetooth version helped me.
As a workaround I use an old Galaxy S7. This has Bluetooth version 4.2. An S5 with version 4.0 also works. After looking at this list, an iPhone 7 should also work: https://handygad.de/howto/bluetooth-version-herausfinder/
The problem starts with Bluetooth version 5.0 and higher. These smartphones are affected.
Describe the bug the issue occures, when i connect from my iphone via bluetooth. Every time i press Play, e.g. In music, the Volume immediately switches to 100%. When i reduce the volume, the volume is back to 100% at the next Play Button press.
