Sound is very distorted (only) when connected to macOS
Opened this issue · 3 comments
In my setup I discovered a very strange behaviour: bt-speaker works fine on the Raspberry Pi 3 (USB Audio, USB Bluetooth Adapter, Wi-Fi and internal Bluetooth disabled).
However when I try to connect from a Mac (macOS), the sound is very distorted. This cannot relate to the known Raspberry Pi Bluetooth/Wi-Fi issues (as other devices work), but may be a missing piece in the decoder code.
When I change the play_command to cat > /tmp/out I can save the decoded stream and later play with aplay -f cd /tmp/out. I’ll attach the file, which may give an indica
tion what goes wrong here… (you can play them with aplay -f cd out.pcm)
(Playing A2DP via BlueALSA/BlueALSA-aplay works also fine, for all devices including the macOS ones)
I have the exact same problem. Working on a mb pro 2014 model, MacOS 10.14.2 (18C54)
Any updates? Facing same problem on macOS Mojave, on MacBookPro Late 2015 15".
I avoided this problem by using BlueALSA (and its own codecs) and a very small bluetooth-agent instead of these backported ones: https://github.com/nicokaiser/rpi-audio-receiver
