A problem in setting speed on SB16 cards was reported. The fix for the SB16 is the following: in sb_dsp.c, function dsp_speed(), add the following lines static int dsp_speed(snddev_info *d) { u_char tconst; u_long flags; int max_speed = 44100, speed = d->speed ; + if (d->bd_flags & BD_F_SB16) { + RANGE (speed, 5000, 45000); + d->speed = speed ; + sb_cmd(d->io_base, 0x41); + sb_cmd(d->io_base, d->speed >> 8 ); + sb_cmd(d->io_base, d->speed & 0xff ); + sb_cmd(d->io_base, 0x42); + sb_cmd(d->io_base, d->speed >> 8 ); + sb_cmd(d->io_base, d->speed & 0xff ); + return speed ; + } /* * only some models can do stereo, and only if not * simultaneously using midi. At this point I am not sure if changing speed works on the SB3.X -- if someone wwants to test... I don't have this card at the moment. Cheers Luigi
