Is this correct ? > No, sorry. set_tone had to be added, because the stv0900 can also > operate in DiSEqC envelope mode (connected to DSQIN of the LNBH24). > In this mode set_tone of the LNBH24 has to be used. ok, you right. But seems like "fe->ops.set_tone = lnbp21_set_tone;" override ".set_tone = stv090x_set_tone," and stv090x_set_tone never used. Is this right ? Also please check our logic. We set override_clear=LNBH24_TEN in cx23885-dvb.c i.e. we disabling 22kHz logic in LNBH24 and all 22kHz logic driven from one place ( stv0900 ). This more clear for debugging (hardware and software ). This problem is reported by one of our customer. Your changeset 13673:75331e740f61 is broke 22khz tone functionality on our cards. We need to find compromise. Reverting the patch is not a problem ( in this case we need to remove override_clear=LNBH24_TEN). -- Abylai Ospan <aos...@netup.ru> NetUP Inc. -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
