Thanks for the pointers. Thats 2,000 lines of code that is about as clear as mud! (and I've written audio drivers before). There is no mention of Bluetooth in these drivers, and no indication how to switch into bluetooth mode. Obviously gta01 was very different, and it is not even clear that the gsmbluetooth.state even worked on a gta01, at least I've never seen any gta01 user claim they had it working. I really don't see how we are supposed to figure this stuff out, without any help from Openmoko. This is a core piece of functionality for a GSM phone guys! Especially in a state where handsfree devices are required whilst driving. I would appreciate a little help from Openmoko to provide a working example of routing the audio to/from a BT headset during a call. I think they may need some help from Wolfson to figure it out! As I said there seem to be no equivalent functions in gta02's alsa settings to match the ones in gta01 that were used to switch into BT mode.
