@erotavlas, thanks but that didn't work for me with an ASUS dongle with the same chip in it. :-(
tim@atom:~% lsusb | grep ASUS Bus 003 Device 003: ID 0b05:17cb ASUSTek Computer, Inc. http://www.ebuyer.com/623493-asus-usb-bt400-mini-bluetooth-4-0-usb-adapter-usb-bt400 "Asus USB-BT400 - Mini Bluetooth 4.0 USB Adapter" I have the same problem of no sound in or out. ======= Quoting the article in case it moves/vanishes: ----- It has come to our attention that there are some issues on certain Linux systems with regards to using Headset Profile and Hands-Free Profile with our USB Bluetooth Adapters. The issue stems from a lack of support for these profiles on the Broadcom BCM20702 chipset found inside our device, unless a proprietary firmware file is loaded into it to enable this functionality. The steps to install the firmware are as follows:Screenshot from 2014-06-23 17:34:49 Open your favorite terminal Run the following command to download the firmware file: wget https://s3.amazonaws.com/plugable/bin/fw-0a5c_21e8.hcd Copy the firmware file to the /lib/firmware folder: sudo cp fw-0a5c_21e8.hcd /lib/firmware Reboot New kernel versions have moved the location in which the firmware file has to be installed. The instructions that follow are for kernels 3.18 and newer Open your favorite terminal Run the following command to download the firmware file: wget https://s3.amazonaws.com/plugable/bin/fw-0a5c_21e8.hcd Create the directory /lib/firmware/brcm sudo mkdir /lib/firmware/brcm Copy the firmware file to the /lib/firmware/brcm folder and rename the file to BCM20702A0-0a5c-21e8.hcd: sudo mv fw-0a5c_21e8.hcd /lib/firmware/brcm/BCM20702A0-0a5c-21e8.hcd Reboot That’s it! HFP and HSP profiles should now work without issue! We have also heard of some reports that these steps can solve some issues with other profiles, like A2DP, but have been unable to reproduce the issues. It is possible that newer versions of BlueZ and the Linux kernel have fixed these issues, and that is why we are not seeing them any more. UPDATE: These steps will also fix many incompatibility issues with certain A2DP devices, such as Bluetooth Headsets and Speakers. If you are having trouble pairing your Bluetooth Audio device to your Linux PC, this firmware file will likely fix your issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/962082 Title: Profiles that require duplex audio like Head Set (HSP) and Hands Free (HFP) do not work on machines with Broadcom BCM20702A0 Bluetooth chips To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/962082/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
