[linux-dvb] Switching mono/stereo at runtime in saa7134 (audio_ddep) ?

This might be OT, since it concerns the analog bits of the saa7134
driver. If so I'd be grateful for directions to the correct forum.
I experience a "warble" in the audio on some (weak) NICAM stereo
channels. The only way to make the sound bareable is to load the kernel
module with audio_ddep=4 (I'm in Norway). This disables the nicam
sound and uses the old-fashioned mono. I'm wondering if there is a way
to turn the NICAM sound back on selectively without disturbing my
recording ? I.e. I would like the effect of reloading the saa7134
module without the audio_ddep option, without actually unloading the
This would of course be unneeded if the automatic switching between mono
and stereo on a weak signal was a tiny bit less trigger-happy,
suggestions for how to adjust the thresholds would of course be even better.
