Hi
Im running:
FreeBSD 4.0-RELEASE #4: Tue May 22 20:11:05 BST 2001
kevin@quota.unseen.org:/usr/src/sys/compile/QUOTA
on a:
CPU: Pentium III/Pentium III Xeon (746.76-MHz 686-class CPU)
Origin = "GenuineIntel" Id = 0x681 Stepping = 1
with a:
bktr0: <BrookTree 848A> mem 0xf4301000-0xf4301fff irq 9 at device 15.0 on pci0
bktr0: Detected a DPL34193?-\M-G8 at 0x84
bktr0: Pinnacle/Miro TV, Temic NTSC tuner, dpl3518a dolby.
full dmesg attached.
It is an early Hauppauge WinTV/FM Radio card. It has an FM aerial, a TV
Aerial, a comp video and an external audio source pluged into it.
I am having problems tunning frequencies on it both TV and Radio, however
ill stick to trying to solve the simpler radio issue here.
I have taken Tim's tuneradio program. It compiles relativly cleanly:
9 root@quota:/usr/local/src/tuneradio/ > cc -o tr tr.c
tr.c: In function `main':
tr.c:86: warning: passing arg 2 of `signal' from incompatible pointer type
tr.c:86: warning: comparison between pointer and integer
tr.c:90: warning: passing arg 2 of `signal' from incompatible pointer type
tr.c:90: warning: comparison between pointer and integer
I added some debuging to it (attached) and here is the output, and some
comentry of what I hear:
10 root@quota:/usr/local/src/tuneradio/ > ./tr
DEBUG: Opening dsp device
# lots of static at normal volume
DEBUG: Set internal audio
# silence
DEBUG: Get mode
# silence
DEBUG: Set mode - mono/afc
# silence
DEBUG: Set frequency
# 1/2 a second of the line in then silence
^CShutting down...
DEBUG: Set internal audio
# lots of static at normal volume
DEBUG: Set unmute audio
# lots of static at normal volume
DEBUG: close device
# silence
I set the default station to 95.8 (int frequency = 9580;) a very local
station that could be recieved even if the aerial wasnt plugged in.
So im very confused! Any help, suggestions, ideas appretiated!
Thanks
Kevin
