Hi guys, a newbie linux user here. So, I think this is a bluez bug but what happens is this…

A lot of times, when i connect my bluetooth headphones(Sony-WH-CH710N) with my fedora KDE (5.25.5), mostly after a pause or so, the headphones stop working… and after sometimes, the headphones just crash(I hear a “tik” and then the light starts to blink and no buttons work so i have to switch it off and turn it back on)… in the system logs, i feel this is the chronology:

Transport Acquire() failed for transport /org/bluez/hci0/dev_30_53_C1_67_B1_8C/sep2/fd10 (Input/output error)
fedora pipewire[1429]: pw.node: (bluez_output.30_53_C1_67_B1_8C.1-79) idle -> error (Received error event)
fedora wireplumber[1431]: (bluez_output.30_53_C1_67_B1_8C.1-20) suspended -> error (Start error: Operation not permitted)

I have really no idea what else information do you guys need but feel free to ask…

Probably this problem can be caused by the Linux kernel which suspend the Bluetooth adapter (it can be connected as a USB device) because it considers the device inactive. Can you show the output of the lsusb command?

Your Bluetooth adapter is listed here as a USB device. It’s possible to prevent the Linux kernel from suspending this device by adding the following udev rule to /etc/udev/rules.d/50-bluetooth.rules:

ACTION=="add", SUBSYSTEM=="usb", ATTR{idVendor}=="0bda", ATTR{idProduct}=="b001", ATTR{power/autosuspend}="-1"
