Description
Attached patch for DirectX Sound adds the ability to specify device(s) to use, honoring independent pcm and passthru settings. Useful in Vista and Windows 7 because they represent analog and digital outputs as separate devices.
Devices are configured on the usual global settings page either by name prefix or by number (as shown by dxdiag). E.g. "DirectX:Digital Audio" or "DirectX:2". If the device ID is wrong or missing, the system default device is used. Only the default "Primary Sound Driver" is pre-populated on the settings page; it's up to the user to enter other device names.
Other fixes:
- Set 48k samplerate for passthru (MS requirement) - patch for winaudio also attached.
- Remove semi-redundant part of underrun detection, because it sometimes caused audio output to hang. The remaining timestamp-based detection works fine.

Replaces original patch. Instead of removing the underrun detection, fix what causes the hang.
