I am a retired software engineer with experience in a multitude of areas including managing AWS and VMWare development environments. I bought a relative a mini-PC a year ago and have become passionate about the technology and its potential to change how we deploy software.
Hey Michael! Great resource to troubleshoot audio issues on a pi! It really covers a lot.
Unfortunately I seem to have an issue that is not described anywhere and it’s getting worse by the minute! I run a RPi5 8gb in an Argon NEO 5 case with a 512GB Transcend NVMe SSD installed. I used it with a keyboard, mouse and speaker connected via bluetooth. I use it a lot as an audio streaming device. All was running fine until some time ago when the audio started cutting out for very short moments (<1Sec). I found out that when I disconnect all bluetooth devices it stops and when I (re)connect them again it starts again.
Do you have any idea what could be causing this?
One possible cause is a conflict between BT and WiFi. Apparently they both share the 2.4 Ghz band and this can lead to conflicts.
Another possible cause is the SSD. Certain SSDs may emit EMI, affecting BT performance.
Some questions:
1. Is the Raspberry Pi connected to a Wi-Fi network during audio streaming?
2. If using Wi-Fi, is it operating on the 2.4 GHz or 5 GHz band?
3. What is the exact model of the Transcend NVMe SSD?
4. Has the Raspberry Pi OS been updated to the latest version?
5. Do other Bluetooth audio devices exhibit the same issue when connected to the Raspberry Pi?
6. Are there any USB 3.0 devices or other potential sources of interference near the Raspberry Pi?
Two things I would try right away btw
– patch if you haven’t and just try rebooting – I have found sometimes computers act weird if they are not rebooted once in awhile.
– try only using the 5 Ghz band if possible
