it is ok, it just auto enumerates the next available minors for the dsps
and mixers. Use the index=N option to have it specified.

we have only Dual FM (A2) here and you should have BG-NICAM.

Didn't notice anything yet, except audio is delayed for about 2 seconds
also on previously fast tuners (FM1216/I hm) and the tda8290/tda8275a
combo, always much slower anyway, has a short crack after changing a
channel, likely automute timing is too short now.

That is not unusual after such detection changes, timing was always
tricky, but will start some more longish analog recordings next days.

That the gpio triggered antenna switch on DVB-T doesn't work intrigues
me more, but don't have that card variant.
