I have heard this can happen if the audio device you are addressing is not recognized by Linux. Someone we know got this result attempting to use their onboard audio chipset which was not.
For them, this was resolved by installing an additional audio card, such as the cheap and readily available Diamond SX71, which is cited on *Ubuntu* sites as fully functional under that OS. Probably would work under SuSE, as well.
If you are using the native ALSA wave player, you likely already know how to determine audio1, audio2, et. al, by the command, aplay -l
Just in case, here's a link: Aplay - ALSA wiki
