I'm running Mythbuntu 8.04 (kernel 2.6.24-19 i think). When I have a clean image with clean modules, I get the following for cat /proc/asound/cards (from memory)

0 M1010LT
1 Conextant cx88
2 Conextant cx88_1

Under this configuration, the analog tuner of the card shows nothing but static on every channel but the sound works and is captured in the backend under /dev/dsp1 and /dev/dsp2.

When I upgrade the v4l-dvb drivers using the following method

sudo apt-get install gcc linux-headers-2.6.24-19-generic mercurial
hg clone http://linuxtv.org/hg/v4l-dvb
cd v4l-dvb
make && sudo make install && sudo reboot

the analog portion of the card works but cat /proc/asound/cards shows only

0 M1010LT

and the sound is not captured because /dev/dsp1 and /dev/dsp2 does not exist. This is because module cx88_alsa is not loading. When I try and sudo modprobe cx88_alsa I get a FATAL error complaining about version not agreeing. Apparently the update to v4l-dvd does not also update the cx88_alsa module.

I am not a linux guru and really need some help with this. Does anyone have an idea of how to fix this?

Thank you,
JA
