Re: No FM for STB TV+FM ? (bt878 + phillips tuner)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



	I thought I'd seen this mentioned before so i searched my archive. 

	The fm radio portion of the tuner works, but only if you first tune the
radio to a frequency above 400 or 500 or so mhz, and then try to tune a
regular station. Then it works. 

	If you have this card, you *must specify the tuner type, or nothing
will work. Even if you've specified card=40. There are defiantely more
than two kinds of STB tv tuners, we probably ought to catalog them and
make sure they have their own definitions, and make it clear in the card
list that the 3dfx desktop tv is the same thing as the stb desktop tv. 

	Also - I've noted in the past that when the fm tuner portion of a TV
card is muted, as with fmtools executing "fm off", the balance of the
volume ends up with the right channel muted and the left channel at 64
or so %. At the time it was suggested that the fm tuner applications
were at fault, and at the time i could accept that. 

	But with bttv 0.7.54, with the tvmixer module loaded, if i, with aumix
or any other OSS mixer, take the volume of the card all the way down to
zero, i get the same effect as "fm off". These applications don't know
video4linux from adam, so I doubt they're doing anything improper with
the videodev interface. 

	My current work around for this issue is to never mute the fm tuner. I
just set the volume to 1%. This works fine, since it's inaudable below
about 30% anyway. But if i ever do mistakenly bring the volume down to
0%, I have to fire up aumix in interactive mode and manually realign the
balance. For some reason, specifying the left and right volumes on the
command line, and i tried with more than one command line oss mixer,
doesn't work. 

	Just wanted to throw the information out there with a few thoughts of
my own, as usual. I apologize for having insufficent programming skills,
to the extent that i'm not able to make head or tail of what's going on
in the code, let alone fix it. Thanks for everything that *does work,
tho.
