WinTV-PVR .. well I wasn't shocked. the audio does not init with
the default driver. this driver will init
the sound (that's sound on a cable to "line-in") but it won't compile
for the 2.4.20-19 kernel I have installed. ( it does work on the 2.4.19
kernel I have on the older box)
First I totally don't understand why I can't get the audio
device on the capture cards. the PCTV and ATI cards to run audio on the
a jack that I can plug into "line in"
For some reason, recording audio in my MSI (via chipset) integrated
motherboard resulted in terrible clicks and buzzes. I reproduced
this with the command line app "recorder" so it's either a bad
motherboard or a bad driver.
Luckily, disabling the onboard sound card and installing another I had
laying around solved this problem. I did however need to lower the
"igain" because the first audio I recorded was badly distorted (over
but on the
audio-from-the-card track, I'm lost. If I manually "insmod btaudio" the
card is recognized, but I can't seem to use it. the dmesg lists
dsp0 and dsp1
but /dev/dsp2 and /dev/dsp3 do not exist.
I don't know how to create a new device, or what the correct way to do
after I load that module the BT878 does show up in
gnome-volume-control ,but not as stereo but as 3 separate mono
channels, you can't select more than one as the record device. but that
doesn't matter, because I don't get audio on any of them anyway.
]# dmesg |grep btaudio
