> I have these drivers: sound - oss, esd ; video - x11, xv, sdl

> The one using esd audio driver makes crackling sound (even when playing
> alone as I start that first).

> If I reverse the order of the commands then the second one fails to give
> audio with the error message :
>
> SDL: using esd audio driver
> SDL: Unable to open audio: No available audio device
> couldn't open/init audio device -> NOSOUND
> Audio: no sound
>
> I am wondering why the order matters and also why esd gives degraded sound
> output.
