A few people (including myself, since a few days after the release of 0.17) have noticed audio device errors using Hauppauge 350s with no sound card on MythTV 0.17. Generally, in this configuration, when you try to watch TV or view a recording, you get an error message stating the device /dev/dsp (or whatever) doesn't exist. After selecting "watch without audio" the video and audio then work just fine. Problem is, the error message pops up whenever you want to view something. This wasn't happening in 0.16.
This is related to the fact that the audio out on the PVR 350 is not a "regular" audio device. Myth seems to be expecting to find such an audio device and complains when it can't. A fix (thanks to Mary from mtu.edu) is to load the snd-dummy module. In my case, I simply issued the command "modprobe snd-dummy". The module sets up a dummy alsa device which then MythTV thinks it is controlling, and voila, no more error messages. I thought this "fix" should be recorded for posteriority...
