Comment 7 for bug 50600

I experienced the same thing, the inbound audio is discontinued after some time although the callee can still hear me clearly.

Hardware used: Motorola H350 bluetooth headset, Sitecom CN-500 USB Bluetooth Dongle with CSR chipset

I also tried the new implementation of the bluetooth-alsa project called plugz. I could get it to work in terms of recording sound from my headset and playing that file on the headset via aplay but i can't use it since my main interest of using a bluetooth headset lies within placing calls over skype.
Since i'm using the amd64 version of Feisty i can't get skype to work properly with the new bluetooth-alsa implementation, it keeps complaining that it is missing the library libasound_module_pcm_sco.so. I copied the contents of a debian deb package for bluetooth-alsa and libsbc into /usr/lib32 but still no luck.
