** Description changed: After suspend (either manually or automatically), every time I connect my phone to the computer through bluetooth, it always disconnected after several seconds. Inspecting hcitrace from btmon, I got: ``` < ACL Data TX: Handle 21 flags 0x00 dlen 16 #209 [hci0] 121.395244 - L2CAP: Connection Response (0x03) ident 16 len 8 - Destination CID: 0 - Source CID: 68 - Result: Connection refused - PSM not supported (0x0002) - Status: No further information available (0x0000) + L2CAP: Connection Response (0x03) ident 16 len 8 + Destination CID: 0 + Source CID: 68 + Result: Connection refused - PSM not supported (0x0002) + Status: No further information available (0x0000) > ``` Often, the symptom is when I play audio from connected phone, I didn't hear the sound from my headset connected on my computer, even though I maxed out volume on the phone. The problem does not occur when the computer rebooted.
