V4L/DVB (12490): Report only 32kHz for ALSA
There are several reasons: - SAA7133/35 uses DDEP (DemDec Easy Programming mode), which works in 32kHz only - SAA7134 for TV mode uses DemDec mode (32kHz) - Radio works in 32kHz only - When recording 48kHz from Line1/Line2, switching of capture source to TV means switching to 32kHz without any frequency translation Signed-off-by: Oldřich Jedlička <oldium.pro@seznam.cz> Acked-by: hermann pitton <hermann-pitton@arcor.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
