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