I JUST installed Hardy, and have had a ton of problems. I can't play audio files anymore, at all, whether it's just basic sending/ receiving chat noises for pidgin, or music files in Rythmbox. In fact, Rythmbox crashed after I tried a few different files. The only sound/ video working is with youtube, that I've seen so far.
Every time I try to play a video/sound file with totem mplayer, I get this message
Failed to connect stream: Invalid argument
With videos, the video will flash up for a fraction of a second, then I will get that error.
I have an Inspiron 530,Intel®Pentium® dual-core processor E2160 (1MB L2,1.80GHz,800 FSB), 128MB NVIDIA GeForce 8300GS, if thaat helps anyone.
This is incredibly frustrating... please, if anyone knows how I can get my sound/ video back, I'd be very grateful to hear it.
