--- Comment #47 from Iván <[email protected]> ---
Confirming on Kubuntu 26.04, kdeconnect 25.12.3-0ubuntu1, PipeWire 1.6.2, bluez
5.85.
Hardware: CSR 4.0 USB dongle (0a12:0001), Creative Sound Blaster GS3 speaker,
A2DP/SBC.
Symptom: heavy stutter at stream start, then intermittent dropouts. Did not
happen before upgrading from kdeconnect 23.08.5.

btmon shows back-to-back HCI Inquiry commands (10.24 s each, restarted
immediately after Inquiry Complete) for as long as kdeconnectd runs;
`bluetoothctl show` reports Discovering: yes. pw-top reports zero xruns and
hciconfig zero HCI errors during the dropouts, so the loss is on the air,
consistent with comment #26's analysis.

Killing kdeconnectd stops discovery instantly and the audio is clean.
`kdeconnect-cli --disable-backend BluetoothLinkProvider` resolves it while
keeping the LAN backend working.

(Diagnosis assisted by Claude; all measurements below were taken on my machine
with btmon, pw-top and hciconfig.)
