MythTV and ubuntu...help!

pikohn · 09-15-2006, 10:42 PM

Hello,

I'd like to start off by saying hi to all the linux gurus out there...i've been using linux on and off for about 6 years now, and recently decided to make it my main desktop. Everything was going good, until I tried to get my tvcard working with mythtv. I've read the how-to's, followed the instructions, but I still can get myth to work. I don't know if it's because the card is not supported or because I did something wrong.

Here's is the error I get

Code:

Welcome to LQ!

How have you tried to set up MythTV?
When I did it, I had to install the mythtv-database package using aptitude first, and then install mythtv.

Also, what tv card do you have? Try "lspci" to see that it is detected, and make sure that you load the correct drivers for it.

I have written how I got my TV card working (Dvico Fusion HDTV DVB-T Lite) Here. Obviously, your channel settings will be different, but you can cross that bridge when you come to it.

I hope this helps

I went to your guide and I have the same card that you have...a bt878. The problem is I'm having trouble installing v41-dvb here is the the error:

I'm not sure what I need to do to fix this...

Sorry, I have no idea...

It looks like you have a sound problem. Have you got a sound card setup?

I looked in my /usr/src/v4l-dvb, and I don't have the aci.c or sound_config.h files, so I don't know why you need them.

IBall · 09-21-2006, 09:22 PM

Pikohn,

Did you ever get this working? I upgraded the kernel from 2.6.15-25 to 2.6.15-27 using apt-get, and now I get the exact same error when
compiling the v4l drivers.

--Ian

IBall · 09-22-2006, 02:04 AM

After many hours of research, I found that the problem lies with the ACI mixer module.
The solution is to disable the ACI mixer module. In the /usr/src/v4l-dvb/ directory, enter the following command:

Code:

make menuconfig

Navigate to "Audio Drivers for Multimedia", and move the highlight to

Code:

< > ACI mixer (miroSOUND PCM1-pro/PCM12/PCM20)

Press "N" to ensure that this module will not be compiled, and then exit (See Screenshot). Save the changes, and then run "make" again. Hopefully, everything should now compile correctly.

I hope this helps

NOTE to all kernel upgraders: Make sure you run make distclean before you try to recompile v4l-dvb for your new kernel. I made the mistake of not doing this and it still uses the old kernel headers.....

make distclean cleans all files and returns you to a fresh slate.

@Iball, that is an interesting solution, is it possible that you aren't looking at the right header files? It seems as if it can't see the headers for definitions.

I found that solution on the Linux TV mailing list Here.

It was trying to compile against the correct kernel version, but looking at the file it was complaining about (/usr/src/linux-.../sound/oss/sound_config.h), the constants in the error messages are not declared in that file. It looks to me that someone has stuffed up somewhere - either the Ubuntu developers have removed those constants from sound_config.h, or the Linux TV developers are using constants that aren't in sound_config.h (possibly they were depreciated in a previous release, and removed in this one ??)
