As of Sept17+ some builds have been implemented with the fix by the OPs, not sure if CyanogenMod has done it yet.
Edit Sept-19-2012 11:04pm: Fix has been implemented by CyanogenMod, it looks like the 48000 sampling rate is not required. I've tested it too and all audio works(with just 44100) except during calls and plays the audio on earpiece of the phone/device instead of streaming it to BT earphones. See Post by budjb.
××× Workaround ×××
I notice that during a call if you turn OFF the Bluetooth earphone while connected to your device(phone) then turn ON the BT earphone it'll connect and also stream the phone call to BT earphone. :screwy:

[URL="http://en.wikipedia.org/wiki/Sampling_rate"]Info about sampling rates:[/URL]
[B]44,100 Hz[/B] Audio CD, also most commonly used with MPEG-1 audio (VCD, SVCD, MP3). Originally chosen by Sony because it could be recorded on modified video equipment running at either 25 frames per second (PAL) or 30 frame/s (using an NTSC monochrome video recorder) and cover the 20*kHz bandwidth thought necessary to match professional analog recording equipment of the time. A PCM adaptor would fit digital audio samples into the analog video channel of, for example, PAL video tapes using 588 lines by 3 samples by 25 frames per second. Much pro audio gear uses (or is able to select) 44.1*kHz sampling, including mixers, EQs, compressors, reverb, crossovers, recording devices and CD-quality encrypted wireless microphones.
[B]48,000 Hz[/B] The standard audio sampling rate used by professional digital video equipment such as tape recorders, video servers, vision mixers and so on. This rate was chosen because it could deliver a 22*kHz frequency response and work with 29.97 frames per second NTSC video - as well as 25 frame/s, 30 frame/s and 24 frame/s systems. With 29.97 frame/s systems it is necessary to handle 1601.6 audio samples per frame delivering an integer number of audio samples only every fifth video frame.[6] Also used for sound with consumer video formats like DV, digital TV, DVD, and films. The professional Serial Digital Interface (SDI) and High-definition Serial Digital Interface (HD-SDI) used to connect broadcast television equipment together uses this audio sampling frequency. Much professional audio gear uses (or is able to select) 48*kHz sampling, including mixers, EQs, compressors, reverb, crossovers and recording devices such as DAT.Sent from my ♛ SGH-T989 ♛ w/CM10-Hybrid PA v2.14(9-22-12) by: michinohatoresu using XDA app.
