Bryan, Chris,
excellent work, no crackling noise anymore. Picture quality for
composite is also good, s-video is b&w.
BUT... the audio for both composite and s-video is from the tuner.
MY VCR is connected to both composite and s-video and the antenna is
also wired via the video recorder.
I _can_ have the matching audio by choosing the "VCR channel" of the
tuner...
My card:
tveeprom: Hauppauge: model = 26034, rev = C197, serial# = 7702916
tveeprom: tuner = LG PAL (TAPE Series) (idx = 97, type = 55)
tveeprom: tuner fmt = PAL(B/G) PAL(D/K) (eeprom = 0x44, v4l2 = 0x00000e07)
tveeprom: audio_processor = MSP3400C (type = 4)
pal=G

I spent my morning looking at why the audio on my svideo and composite
inputs has clicks and stuff in it. I've modified our
cx25840_set_audio_input to more closely match the windows driver. The
main difference is the mutes on line-in; we now unmute AC97, PAR, and
SRC1 like the windows version does.
I've also removed a lot of places where we toggle the microcontroller on
and off, and only turn it on after selecting tuner audio. This is also
came from the windows driver.
Third, I fixed where I had a typo in my 5/31 email. I meant to say
0x478 write4 0x6650021f, but I said 0x64... The difference that a 2line
luma comb filter can be used by the adaptation algorithm in addition to
the 3line.
I've also got:
-- CH2_SRC is now set to 0 instead of 3 when selecting the tuner input.
This is because CH2 isn't actually used, and I think it reads a little
better this way. The line could actually be removed altogether.
-- CH2 or CH3 is powered down when not in use by the selected input.
-- A function to power down all units is included but #defined out.
I can break these up, but I don't see any potential problems except for
all the changes to the MICROCTRL on/off.
