Summary	07765: sfrush, sfrushrk and clones: Distorted sound when loading from save state
Description	Similar to the original no sound when loading from save state issue (ID: 07724), the sound is now distorted when loading from save state. It looks like the excellent sound streams update to 0.225 has introduced this new issue.
Steps To Reproduce	1. Set autosave 1 in mame.ini file 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 6. Game resumes from save state but audio is distorted

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.
