AI Thread Summary
Bluetooth speakers can be successfully paired with a Raspberry Pi 4, and users can select them as audio output through the desktop interface. The speaker's profile typically appears as "High Fidelity Audio (A2DP Sink)." However, issues may arise where the speaker remains silent during media playback, with only brief sound when adjusting the volume. Troubleshooting steps include ensuring the proper Bluetooth driver is installed on the Raspberry Pi. While some users may successfully use Bluetooth earphones, specific modules may still be required for speaker functionality. A recommended solution involves adding the user to the Bluetooth group with the command "sudo usermod -a -G bluetooth pi," which can resolve audio output issues after a reboot.

  • I am able to pair my Bluetooth speaker to my Raspberry Pi 4.
  • I am able to select it as the current audio output by right clicking on the "speaker" icon, top left of desktop.
  • Under "device profiles" the speaker's profile is shown as "High Fidelity Audio (A2DP Sink)".
  • But when I play any media, the speaker is silent.
  • Each time I press the volume up (+) key on the speaker, it plays the media for a short time (a fraction of a second).

Anything I can do to troubleshoot and fix this?

I haven't done anything like this before but the first thing that I would do is check to see if you have a proper driver installed on the Pi.

At least some of the driver stack is installed and working properly, because I am able to use Bluetooth earphones (2 or 3 different makes) without any problem.

I could still be missing some specific module that is needed for the speaker, though. I am googling this problem. The suggestions I found so far haven't helped.
 

Thread 'Windows 10 Now Not Supported'

Well, the date has now passed, and Windows 10 is no longer supported. Hopefully, the readers of this forum have done one of the many ways this issue can be handled. If not, do a YouTube search and a smorgasbord of solutions will be returned. What I want to mention is that I chose to use a debloated Windows from a debloater. There are many available options, e.g., Chris Titus Utilities (I used a product called Velotic, which also features AI to prevent your computer from overheating etc...

Thread 'Cooling a processor chip'

I have been idly browsing what Apple have to offer with their new iPhone17. There is mention of 'Vapour cooling' to deal with the heat generated. Would that be the same sort of idea that was used in 'Heat Pipes' where water evaporated at the processor end and liquid water was returned from the cool end and back along a wick. At the extreme high power end, Vapour Phase Cooling has been used in multi-kW RF transmitters where (pure) water was pumped to the Anode / or alternative Collector and...
