Question Incompatibility: dell 3050sff + bluetooth

[maxy0440yxam]

Good morning, i'm experiencing a very strange behaviour of my dell 3050sff (second hand) i3-6100.
It has no bluetooth, so i bought a usb bluetooth dongle (4.0 tplink).
When i connect my "speakers" (i have 2 type of "buds", a bluetooth receiver with 3.5mm plug, and a headset), they seem to "lose" the signal for some seconds while playing youtube, using skype, and so on.
So i bought another bluetooth dongle (5.0 with no brand), same behaviour.
Then, for "the last chance", i bought another 5.3 dongle. nothing changed.
All of these "speakers" works perfectly with my Macs (M1 mini and air)
I tried with windows 10, and ubuntu (both full updated).
I tried to move from the dongles from the front usb to a usb hub near my monitor.
While windows finds the buds in a few seconds, ubuntu takes a lot for this, and often i have to restart the bluetooth from control panel several times before it recognizes, but when ubuntu recognize it, the behaviour it's the same: in a 3 minute video or skype call, at least 10 "lack of signal".
I tried with a intel nuc with windows 10 with an internal bluetooth, it finds almost immediately the buds and it has no problem.
I don't really know how to solve the problem, do you have some ideas?
apart the bluetooth issue, the pc works perfectly.
thank you

Welcome to the forums, newcomer!

You might want to make sure that your prebuilts BIOS is on the latest version. Then check to see that your OS is also up to date. As for your BlueTooth dongle's, can you pass on a link to all of them? Look into Device Manager and see if anything is flagged with a yellow exclamation mark.

Amazon.it

and the bios and os are updated.
no "yellow marks".
sincerly, now i'm thinking about some strange incompatibilities.
I'm thinking about buying a m2 bluetooth card with an internal antenna, but i'm sick of spending money on this f* bluetooth, maybe it's better than i use this pc for another use...
I searched online but it seems that this dell has no similar issues reported.

Thank you very much for the answer and the welcome!

I have a feeling you might be looking at entry-level Bluetooth transmitters and you might need to look at a more expensive HiFi unit, better designed to work with headphones and earbuds.

In the mean time, you could check connectivity between your ever increasing collection of Bluetooth dongles and earbuds using Nirsoft's Bluetooth Viewer.

You could use Bluetooth Viewer to detect other Bluetooth devices in the vicinity, which might be interfering with your audio connection.

Have you also considered you might be having latency problems due to the speed of your computer?

When I'm playing back FLAC files into a Cambridge Audio DACMagic 100 from an old i5-4670K PC running at 4.3GHz, I get occasional audio dropouts when the 4-core CPU is overwhelmed with other tasks.

The 4670K and Foobar2000 cannot maintain a continous stream of data to the external USB DAC all the time. I have no such problems streaming from my 3800X or 7950X.
