Probably sometimes the broktree driver is loaded first. This makes the
TV card the default device (index 0). You can check this with

cat /proc/asound/cards

You need to reconfigure ALSA to use static index numbers, no matter in
which sequence the drivers are loaded (you can also make sure the
realtek driver is always loaded firs by adding it to /etc/modules, but
I prefer the other way).

Edit some file in /etc/modprobe.d, e.g. /etc/modprobe.d/sound, and add
these lines

options snd_intel8x0 index=0
options snd-bt87x index=1

(if snd_intel8x0 is the driver for your sound card, otherwise change it

After rmmoding the driver and reloading them (or rebooting) the problem
should be gone.
