No - /etc/modules is empty. > BS> If I unload the sound modules manually they do not show in the > BS> list produced by lsmod but if I play a CD sound still works!!! > > Sure. <shrug> On PCs, the audio output from the CD-ROM gets tied > directly into the sound card, goes through the sound card's mixer, and > gets fed to the audio output.

Try, for > example, finding a .au file, and catting it to /dev/audio. Do you get > output then? I have now tried that and, yes, it only outputs when the sound modules are loaded. However I have managed to find a midi file and as I have KMidi I thought to try it. It says 'cannot access /dev/sequencer' so I tried to cat the file to /dev/sequencer and I get 'no such device'. The device is there and it has the same ownership/mode as other audio devices. I tried re-making the audio devices with MAKEDEV. MAKEDEV listed the devices as they were created including /dev/sequencer but I still get the message 'no such device'. I'm a tiny bit closer in that I know that the sound modules do have some effect but there are still more problems than answers. Barry Samuels
