Same problem — programs like Totem and Rhythmbox work fine, but any games (like Warsow, OpenArena or Urban Terror) fail, and also Flash doesn't have any sound.
I have an NVIDIA sound device exactly the same as Vladimir's, and receive exactly the same error as the OP's when launching Urban Terror: ------ Initializing Sound ------ Initializing SDL audio driver... ALSA lib ../../../src/pcm/pcm_dmix.c:864:(snd_pcm_dmix_open) unable to open slave SDL audio driver is "(UNKNOWN)". SDL_OpenAudio() failed: No available audio device Sound initialization failed. -------------------------------- ** Changed in: alsa-driver (Ubuntu) Status: New => Confirmed -- [Gutsy] ALSA lib pcm_dmix.c:864:(snd_pcm_dmix_open) unable to open slave https://bugs.launchpad.net/bugs/150129 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
