Hi list I've been debugging all morning issues with the Parrot ZIK 3.0 (and its two previous model versions) not displaying HSP profile as available. Here is the headset in bluetoothctl: Device A0:14:3D:6B:E6:7F Name: Parrot ZIK 3.0 V3.01 Alias: Parrot ZIK 3.0 V3.01 Class: 0x240408 Icon: audio-card Paired: yes Trusted: yes Blocked: no Connected: yes LegacyPairing: no UUID: Audio Sink (0000110b-0000-1000-8000-00805f9b34fb) UUID: A/V Remote Control Target (0000110c-0000-1000-8000-00805f9b34fb) UUID: Advanced Audio Distribu..

HSP profile shows up eg. in pavucontrol, but is "Unavailable". Digging into it, I found out pulse cannot find a transport for it. Attached is a log file of dbus-monitor when the headset is turned on and automatically connects to pulse. In the log files, when the device connects, I always see "bluetoothd[455]: No valid attributes in request" twice in journalctl. I looked into it (happens in avrpc.c from bluez)... doesn't *look* related but can't tell for sure. Compiled the latest (0f48b7c8) pulseaudio with native bluetooth backend / bluez 5.38-2 on Arch Linux. Bluetooth adapter is an integrated btusb device. Fresh out of ideas. Suggestions? J.
