Hello, Some news about the work on the sound system : I've ported the ES1370 driver since I wasn't able to debug the maestro3 driver on real hardware, and ES1370 is one of the chips emulated by qemu (the only PCI one IIRC). The good news is that I was able to hear some sound ! But the kernel crashes in device_write(), so the next step is to find why and how to fix it. The source code of the kernel is available here [1]. Configure it with --enable-ide --enable-kdb --enable-rtl8139 --enable-es1370 and it should be suitable for qemu (i don't have a ready-to-use image to provide). I've written a test tool that writes a file to dsp0 using device_write() which can be downloaded here [2]. Use it like this :
./sndwrite sample.raw The sound is crappy, it's normal :-). The sample.raw file can be created using cat /dev/dsp > sample.raw on a e.g. Linux system (raw recording). Remember to use gcc 4.0 and not 4.1. Any help debugging is welcome :-). -- Richard Braun [1] http://cvs.sceen.net/index.cgi/gnumach/ (Download tarball) [2] http://devel.hurdfr.org/sndwrite.tgz
