Perry this is great news, can't wait to try out the
tvmixer driver. This is what I would like to use,
getting sound directly off the wintv card; I assumed
it works as well when I am tunning into FM stations?
Since, it is part of the alsa project, I assumed the
/dev/dsp? is still the device which control sound?
On another note, I have two type of wintv cards, one
with msp chip and the other with out msp chip.
Currently I have taken line out of wintv cards into
line in of sound blaster cards for both type of wintv
card. Both are tuned into FM stations. The sound
blaster cards are driven by ALSA driver. The reason I
did this for card which has msp chip on it, is
because I do not know how to take sound directly off
of it; hopefully with your suggestion on tvmixer
driver, I will be able to do it.
current issue with card that has msp chipset and with
module msp3400.0 loaded. It is tuned in on FM
station. Wintv line out is going into line in of
Sound Blaster card:
1. to loud
2. clipping sound
woud like to know if I could by pass msp chip.
would like to know if there is a param to passed to
msp3400.0 that would help with controlling sound
quality.
