2. Launch MAME64.exe and load sfrush
3. Start game to confirm sound is OK.
4. Exit MAME64
5. Re-launch MAME64.exe and load sfrush again

This appears to be a more wide-spread problem. I had it happening with wg3dh, too, which is same driver but different sound hw and with kinst, which is different driver and different sound hardware.
EDIT: Though in the end all of those sound boards use the DMADAC device.

It seems to be worked around by adding a device_post_load to cage with update_serial() and dcs with recompute_sample_rate(), but it seems to point to a more general problem, so I'd be more comfortable if Aaron could look at this.

Should be fixed in next version. Sound streams weren't saving their sample rate.
