Streaming from bluetooth (alsa pcm/bluez issues) #61

Hey there, I installed this as per the instructions on a Raspberry Pi B+ running the latest raspbian 10 release, and I have been having issues with the Bluetooth streaming from my phone. I followed all the install instructions and checked the logs and found some useful tidbits that may help in debugging.

command: ./mpradio.py https://pastebin.com/r9P1irsf

command: sudo systemctl status bluealsa.service https://pastebin.com/sdSRigpM

command: cat /var/log/bluetooth_dev [Wed Dec 30 20:53:04 GMT 2020]: Start Bluetooth played connection

I'm able to broadcast to fm using the test sound and the mp3 files in /pirateradio/. I'm familiar with cmd so please let me know if there's any other info I can provide

Any help would be greatly appreciated!

Huh, after reading the other open issues, it turns out that the Bluetooth audio doesn't work if there are no music files in /pirateradio/. I also encountered the slowed audio, which was fixed by a quick reboot. Not sure why that matters but I would assume it's something to do with the program crashing after it's unable to find files.

There are also stuttering issues with the Pi B+, every 20 ish seconds it loops back about half a second of audio. I will test on a Pi 3 and see whether it is simply low specs. The Pi 3 was on max overclock.

Still occurs with the Pi 3, i have tested the pi_fm_adv program separately with no issues, and playing local files also works fine. I have also disabled wifi on the board. Any way I can debug this? Not sure which log file to look at, or if this would be logged at all.

making a new issue for the stuttering, as the original issue has been resolved
