Working HVR-900 Driver
Well a quick update on the Linux driver for the Hauppauge HVR-900 USB tuner. A quick posting on the Video4Linux mailing list and I got some tips on setting up the unit for NZ. Appears I was using the wrong firmware pack, and I needed to use the v3 firmware set mentioned at the Em2880 page.
Also I was loading the wrong audio modules. I don’t need the em28xx-audio driver for this unit, so the correct modules are -
modprobe em28xx modprobe em2880-dvb
It appears that the USB audio device is /dev/dsp1 so I had to select the correct DSP device when setting up the card in MythTV and now I have fully working audio on DVB-T and Analogue.
Here are a couple of updated screen shots taken from TVTime, without the interference pattern I was previously getting.
So the last step now is to test the card with some of the other cards OpenMedia currently ship, in particular the ivtv driver for the Hauppauge PVR-150 and PVR-500 cards. More later.
