No SDL audio under Linux

SDL Development
1

Hi,

I have a little program playing a wave file. Under Win32 it works but under
Linux I become:

cout << SDL_GetError() << endl; -> No available audio device

if I call it directly after SDL_Init(SDL_INIT_AUDIO).

Sound is working fine under Linux. I’m using the alsa drivers. So my
question is what can I do to get sound working. Do I need a special device
in /dev so I can make a symlink or something like this?

I’m running Slackware 8, Kernel 2.4.18 and alsa-0.5.12a.

Try setting an environment variable called SDL_DSP_NOSELECT to “1”.

Try setting SDL_AUDIODRIVER to “alsa”.

In bash:
export SDL_AUDIODRIVER=“alsa”

then execute your app.
