It worked on an ESS Solo 1 and Crystal Sound Fusion. I have another machine with MediaGX, I will try it on that to see if it works. Did you load all of the OSS modules? For me they did not load automatically, I had to add them in my init scripts (snd-pcm-oss, snd-mixer-oss, snd-seq-oss). For me, with those drivers loaded, I can run both native ALSA apps and regular OSS apps. Linux uses the OSS standard for its native audio driver. I was even able to get two ESS Solo 1 sound cards working in the same machone with ALSA and OSS. -- Doug Chris wrote: > What kind of soundcard do you have?
