From: Hannu Savolainen Subject: SDL uses obsolete OSS features I was trying to compile SDL against the latest OSS version. It appeared that SDL 1.2.7 is using a very old SOUND_PCM_WRITE_RATE ioctl that is obsolete and has been removed from OSS. The right ioctl to call is SNDCTL_DSP_SPEED. Attached is a patch (works with all OSS versions).
