We should not mute the audio input when we stop the codec, because it will interfere with the live uncompressed stream. Signed-off-by:

Fix lack of audio on the MPEG-2 stream of wm8775 based blackbirds. The wm8775 module initializes the audio input at "route 2", which doesn't hold true for all boards. The HVR-1300, for example, uses route 1 for tuner audio, and route 2 for baseband. So we must route the audio to the proper input depending on what video input is being used. Signed-off-by:

Remove the unnecessary BLACKBIRD_UNMUTE calls to the mpeg encoder in cx88-blackbird.c The encoder is never muted, hence unmuting should then only be necessary once after hardware initialization. I tested this from warm boots and cold boots (with long power down time to ensure the sram in the chip is emptied), and found that after the firmware upload the encoder is apparently not muted, making the unmutes unnecessary.

This patch should fix the 'muted audio' and 'raspy audio' problem for mpeg2 streams out of cx88-blackbird devices. Especially mythtv users would find that the audio would often sound bad (aliased, or 'raspy'), mainly related to channel changes, many (all?) other users would find that there was no audio at all in the mpeg data from the encoder chip, unless the audio was manually unmuted. The patch includes the following modifications: Don't actually start the mpeg2 encoder until the device is read from by the application. Wait until the audio is stable for at least 400ms before starting the mpeg encoder. Mute/Unmute the audio when starting/stopping the mpeg encoder. Stop the mpeg encoder when changing parameters and when changing tuner frequency. Add a variable 'mpeg_active' to struct cx8802_dev to allow tracking of whether or not the mpeg2 encoder is active. Load the firmware on cx88-blackbird driver load. Signed-off-by:

ATSC standard-specific firmware is D2633 on both v2.5 and v2.7. Better to auto-select this firmware, overriding ctrl.d2633. Signed-off-by: -

On the s5h1409 demod, the IF frequency for VSB is limited to 44 / 5.38 MHz. Hardcode VSB IF frequency within the driver to 44 / 5.38 MHz. QAM IF frequency remains configurable via attach-time configuration. Acked-by:

If we pass TDA18271_GATE_DIGITAL into tda18271_attach(), it will always try to use the digital demodulator's i2c gate. If we pass TDA18271_GATE_ANALOG into tda18271_attach(), it will always try to use the analog demodulator's i2c gate. If we pass TDA18271_GATE_AUTO into tda18271_attach(), it will try to use the analog demodulator's i2c gate when tuning in analog mode, and it will try to use the digital demodulator's i2c gate when tuning in digital mode.

saa7134 were converted to video_ioctl2, but saa7134_empress weren't. This broke saa7134-empress, since it were dependent of saa7134_common_ioctl.

The pvrusb2 driver tries to keep all device specific attributes in a single data structure in one source file. This change further cleans up how that table is set up. We now try to group everything together for each specific device, and the number of symbols exported from this module has now been reduced to a single global. Signed-off-by:
