about this issue Figured i would try to get help from as meny
sources as possibble. so here is transcript of my post:

12px; color: rgb(132, 132, 132);">I have a Hauppauge hvr 950-q
that I had been using with 10.04 since it came out with no
issues at all(non that i could not fix anyways) had mythtv set
up using mythubuntu and all was great. I upgraded to 10.10
last night and cannot get sound to work during live tv. If i
watch an old recording the sound works. Sound also works
everywhere else on my system. Before the upgrade the audio
setting in the backend configuration of the tv card was set to
/dev/dsp2 this no longer works. if i put it at that(i have to
enter it manually) then i have no sound and if i try to change
Channel the tv feed crashes.<br>
<br>
I have tried /dev/dsp2,1 i even tried /dev/snd/contolC1 wich i
got from browsing around in /dev and found this to point to my
950-q all with same results.<br>
<br>
If i use alsa:default as the audio device in the backend i
still get no sound but i am at least able to change channel.<br>
<br>
everything works in TVTime.<br>
<br>
i am simply at a loss. My next step was going to be a clean
install of 10.10 but i thought i would check here before
taking such a drastic step.</span></div>
