** Description changed: Kubuntu 12.04 here. This system is built for heavy gaming and videos, it has a Zogis GeForce GTX 550 Ti which connected to my TV via HDMI. I'm using the sound card that's integrated into the GPU, I have made it my primary card in alsa by changing "/usr/share/alsa/alsa.conf": defaults.ctl.card 0 defaults.pcm.card 0 defaults.pcm.device 0 became: defaults.ctl.card NVidia defaults.pcm.card Nvidia defaults.pcm.device 7 I have never liked pulseaudio, and alsa does everything I need faster, so pulseaudio is usually the first thing I remove in my installation. sudo apt-get purge pulseaudio However those are the problems I have without pulseaudio: 1) dolphin-emu produces some weird noises randomly. 2) The 2 games I have developed which use SDL for sound have sound distorted and failing a lot. http://cmcgames.darkphear.com/2012/01/yagac.html http://iceroyds.darkphear.com/ Other games that use SDL for sound seem to have the same behaviour. When I run it in the console I have a LOT of: ALSA lib pcm.c:7339snd_pcm_recover) underrun occurred 3) MAME has serious latency in sound (about half a second). It uses SDL for sound too. 4) MAME running old games such as twinbee have a terrible crackling sound that makes it unplayable. There are two lame workarounds for this; one is reducing sampling rate below 22050 (argh!); other is using the alsa oss wrapper : "aoss mame twinbee -audiodriver dsp" which is a little better. I have tried removing the Ubuntu SDL packages and installing SDL from the official page, but it didn't change a thing. The problem seems to be deeper, maybe in libasound2 or in alsa itself. --- AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
