Title:
Audio problems with ALSA
Status in alsa-driver package in Ubuntu:
Expired
Bug description:
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.
