Routing audio between SoC and Bluetooth should be possible through HCI (that is, BT is connected via USB to SoC). The chips shipped in the Freerunners have default eeprom setting (they call it ps keys) to route SCO audio (i think that doesn't affect A2DP) over PCM interface. This setting can be changed but after that one has to issue a special command every time he wants to route the next SCO communication over PCM. 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. -- Be free, use free (http://www.gnu.org/philosophy/free-sw.html) software! mailto:fercer...@gmail.com _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
