Are you sure, that the sidetone is added by the VSTPGA/BTSTPGA? Could you check, if you accidentally left either the analog loopbacks e= nabled=20 (or digital loopbacks)? Check for these: Right1/2 Analog Loopback, Left1/2 Analog Loopback, Voice Analog Loopbac= k, Left/Right/Voice Digital Loopback Could you describe your scenario (uplink, downlink routing, etc)? --=20 P=E9ter -- To unsubscribe from this list: send the line "unsubscribe linux-omap" i= n the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
