Zoltrix Genie TV card (BT 848)

[samung]

Hey,

I have a Zoltrix TV tuner card and I was wondering if it were possible to get this card working in X. I installed xawtv but it dies with an error message,

"can't open /dev/video"

/dev/video seems to be a symbolic link pointing to /dev/video0 which exists and seems valid (as far as I can tell).

I recompiled the kernel for video4linux support. Is there anything else that I'm missing?

Ok, I've got farther this time (still don't have tv working). I recompiled and installed the following modules: i2c, bttv, msp3400, tuner. The i2c and bttv ones seem to be working since I see nice messages from the kernel detecting the hardware. However, I don't see any messages coming from tuner or msp3400.

So, now when I run xawtv, I get static all over (but no errors that I can see). Sound doesn't work either.

Any ideas? I'm running 2.2.17 and X 4.0.1 now and as I said before it's a Zoltrix Genie TV card. It's actually a BT878 chip.

You have

1) got the ariel plugged in
2) tried tuning some channel in

I know it sounds silly, but I failed with #1 when I first started TV in linux.

[samung]

Yes, everything is plugged in since the tv works fine in windows.

Anyway, I've gotten a lot further now. I now have video working and can change channels no problem. I just had to add an option pll=1 like this: modprobe bttv pll=1 radio=1. So, I am almost there.

But sound is still not working. The module msp3400 should be responsible for this. I'm pretty sure the sound processor is an msp3400 since I saw the chip on the bottom of the tv tuner card. I do a modprobe msp3400 and I get no kernel output messages.

I have a Sound blaster Live card using the latest drivers from http://opensource.creative.com/. Any ideas?

Yippee!!! Well, I got audio to work. Well, sort of. I downloaded the latest bttv drivers (0.7.46) and everything seemed peachy but there was still no sound. Tried plugging cheapo speakers in my line-out jack and I could hear sound! So, I guess tv sound doesn't like my digital 5.1 DTT2500 speakers which is weird since all other sound works fine with these speakers (cd-audio, mp3, wav). Any ideas to get tv audio to work with my digital speakers? I have a creative live card.

Thanks for all the help so far, couldn't have got this far without this informative community. http://www.linuxnewbie.org/ubb/wink.gif

I have a similar setup, and I was wondering how to go about trying to get my ATI TV Wonder working in linux. It's a BT878 chipset, which is the same as yours. I'm running RedHat 7.0 with kernel 2.2.16-22. Can you make any suggestions for how to go about it? I've looked at i2c and lm_sensors, but the readme files scared me a little bit with their talk of needing fresh kernel tree headers or something (I'm still a little new to linux). Is that something I should worry about, or should I just go ahead and compile/install i2c, lm_sensors, and bttv (in that order, I assume). Any suggestions, help, or encouragement would be appreciated http://www.linuxnewbie.org/ubb/smile.gif

Thanks,

Yes, you're going to need the latest bttv (0.7.46) & i2c stack if it's a BT878. Although, I didn't see the ATI TV wonder in the list of supported cards, so I'm not sure if you'll be able to get audio. Video should work though. You will need a kernel source tree (I usually put it in /usr/src) to compile the modules. You'd also want it to be a kernel source tree that matches the kernel you are running.

I still haven't managed to figure out how to get tv sound to my digital speakers. Anyone know where I can post this question and get at least some sort of response?

I installed the kernel source along with nearly everything else when I installed RedHat 7, is that sufficient to satisfy the "kernel source tree" requirement? If not, how can I get such a beast?

Well, try compiling the bttv & i2c modules. If you get all kinds of missing header file errors then you probably don't have the tree. Or your tree is not in the default location of /usr/src/linux.

You can get kernels at http://www.kernel.org And remember to use a mirror. Just tar -zxvf or bzip2 (whatever your pleasure) into /usr/src and you should be all set. Remember to get a matching kernel to your current kernel (2.2.16?).

Sorry to be a pest, but I've run into a problem. I grabbed the kernel as you suggested. As route I put a copy of it in /usr/src/ and ran tar zxvf linux-2.2.16 (I've got the 2.2.16-22 kernel). When I run make all for the i2c install, it gives me the following:
grep: /usr/src/linux/include/autoconf.h: No such file or directory
grep: /usr/srec/linux/.config: No such file or directorygrep: /usr/srec/linux/.config: No such file or directorygrep: /usr/srec/linux/.config: No such file or directorygrep: /usr/srec/linux/.config: No such file or directorygrep: /usr/srec/linux/.config: No such file or directorygrep: /usr/srec/linux/.config: No such file or directorygrep: /usr/srec/linux/.config: No such file or directorygrep: /usr/srec/linux/.config: No such file or directory
make: *** No rule to make target '/usr/src/linux/include/rhconfig.h', needed by'kernel/i2c-elektor.d'. Stop.

I've looked for both files, and neither exist. Are they just not in the same places as the makefile expects them to be, or do I have a more serious problem?

Any help is, as always, greatly appreciated http://www.linuxnewbie.org/ubb/smile.gif

Ok, I just re-read the INSTALL file that is part of the I2C package. An untarred kernel tree will not cut it since compiling the kernel generates some files that compiling the i2c module needs.

So, you will have to recompile your kernel since I assume you don't have the original tree that came with the kernel you're running now. This is a pretty big job and way beyond something that I can tell you in this little post.

I was afraid that was the case. I guess I might deal with it eventually, but that's not the sort of thing I decide to do on a whim http://www.linuxnewbie.org/ubb/wink.gif
