I'm trying to make my Santa Cruz work with NetBSD 2.0.2. Actually, it almost
works, it just doesn't produce any sound :

clcs0 at pci0 dev 11 function 0: Cirrus Logic CS4280 CrystalClear Audio
Interface (rev. 0x01)
clcs0: interrupting at irq 11
clcs0: ac97: Crystal CS4297A codec; headphone, 20 bit DAC, 18 bit ADC,
Crystal Semi 3D
clcs0: ac97: ext id 200<AMAP>
audio0 at clcs0: full duplex, independent
midi0 at clcs0: CS4280 MIDI UART

According to PR/18880 and PR/24488, this sound card needs to activate an
external amp. After modifying ac97.c (and a few other files) accordingly,
it works, but the sound is very metallic.

This is not a total surprise, I sometimes have the same problem with Linux.
There is an easy fix : stop then restart playing. Under NetBSD, this
doesn't help.

Any clue ?
