I have a set of motorola s305 bluetooth head phones. These head phones work PERFECTLY on ubuntu 10.04 64bit (high and low quality, microphone as well). I tried Ubuntu 11.04 and the head phones cause a kernel panic (among other problems). Reading the forums and bug lists, this might not be due to these specific head phones.
I have now installed Ubuntu 12.04 on a Asus K53s series and the head phones are both visible and connect, however, there is no sound. With Ubuntu 11.04, sound was possible but only low quality (HSP/HFP) no high quality (A2SP). With Ubuntu 12.04, both HSP/HFP and A2SP show up in the options but when I switch to the head phones as output in the sound preferences there is no sound.
Im using a Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode). hciconfig shows the following:
hci0: Type: BR/EDR Bus: USB BD Address: AE:2D:22:00:FF:00 ACL MTU: 344:12 SCO MTU: 180:16 UP RUNNING PSCAN RX bytes:814 acl:0 sco:0 events:32 errors:0 TX bytes:634 acl:0 sco:0 commands:32 errors:0
There seems to be bug here. Has anyone got these headphones working with both high/low qualities of sound? Thanks in advance.
