| In an attempt to open / allocate AHI for a specific sample format, I've noticed that if I query the HD Audio driver (v6.22) on the X1000 for the bits per sample (AHIDB_Bits) it is never retrieved. It works for other modes so I'm assuming it's not my code -- which is always a surprise.
Is anyone else seeing this? It doesn't appear to really affect anything - the test tone plays etc and I appear to have working audio with one of the HD modes as default so I'm not entirely sure what gives. Any thoughts would be appreciated. _________________

This one is my fault.
The documents for GetAttr say:
LONG AHIsub_GetAttr( ULONG, LONG, LONG, struct TagItem *,
struct AHIAudioCtrlDrv * );
IMPLEMENTATION
Return the attribute based on a tag list and an AHIAudioCtrlDrv
structure, which are the same that will be passed to
AHIsub_AllocAudio() by 'ahi.device'. If the attribute is
unknown to you, return the default.
The HDAudio driver simply returns the default value. This is apparently something I never went back and implemented properly.

Can this affect other things ( like for example AHI_BestAudioID() ) ?
