So DiSEqC (and possibly 22kHz) are probably done using EXTM. > There seems to be no difference if I set the TEN-bit (DSQIN disabled by > writing 0x64 or 0x6c instead of 0x44 or 0x4c). Setting TEN should enable te 22kHz tone immediately. Hm - did you forget to compile or reload the driver? Anyway, let's try whether 22kHz and DiSEqC are generated by the stv0299 in the tuner. Comment out or remove the lines [*] in av7110.c: case 0x000E: /* Hauppauge//TT Nexus-S rev 2.3 */ /* ALPS BSBE1 */ av7110->fe = stv0299_attach(&alps_bsbe1_config, &av7110->i2c_adap); if (av7110->fe) { [*] av7110->fe->ops->diseqc_send_master_cmd = av7110_diseqc_send_master_cmd; [*] av7110->fe->ops->diseqc_send_burst = av7110_diseqc_send_burst; [*] av7110->fe->ops->set_tone = av7110_set_tone; av7110->fe->ops->set_voltage = lnbp21_set_voltage; } break; Does this improve things?
