That sounds like a great workaround, although unless it exposes some digital audio device class entity it sounds like work to stitch it together into something you can pipe audio into. | Unfortunately, the BT earpiece i have here for testing works only with | laptop for now (with the same bluez), with FR i hear only ambient noice. | |> Maybe there's some way to meddle it through the ADC and DAC but other |> than that it doesn't work IIUI. | | Doesn't seem it can be possible on Freerunner because both DAIs are | timed fully independently. Keeping it all digital on USB would be a superior solution. You can get these EDR stereo headsets now it would be a nice feature. - -Andy -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iEYEARECAAYFAkmhIZkACgkQOjLpvpq7dMovZQCfTB6g8096cgSYLo8zTKWxPx4B 41MAn24sE0hte8/ZQ6Xs2pU15uNsx8Ik =HNvI -----END PGP SIGNATURE----- _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
