the rate=48000 is only valid for external analog input and disables
sound from tuner. Have a look at the saa7134-oss mixer under such
You must use default rate of 32000 for dma sound from tuner.
The saa7134-oss is also soon deprecated and replaced by saa7134-alsa.
If you are considering using recent v4l-dvb mercurial stuff, which
should be best for the HVR1300 and reporting bugs on saa7134-empress,
you might still have your old saa7134-oss module around and some others
like the old video_buf now loaded, since not deleted on upgrade.
After make rmmod and rminstall with current v4l-dvb you should delete
such remaining modules on older kernels too before make install.
