Okay, after figuring out that the "pcmplay" in 1.0a2 doesn't open in O_SYNC, I finally got ttsd working as I expected it to. I'm *shocked* that I got the audio overlay patch to work right the first time! I was *sure* something in Hijack would confuse it somehow.

Anyway, no snow here, not sure why you're getting that. Any more information? When does it happen?

I also get the volume spike after it fades down and up. The BG music volume is configurable (well, via #defines) in the audio overlay patch:

/* Audio overlay specific variables */

#define AUDIO_OVERLAY_BUFFERS                           (16)

#define MAX_FREE_OVERLAY_BUFFERS                        (AUDIO_OVERLAY_BUFFERS - 2)

#define AUDIO_OVERLAY_BG_VOLUME_FADED           (0x00004000)

#define AUDIO_OVERLAY_BG_VOLUME_MAX                     (0x00010000)

#define AUDIO_OVERLAY_BG_VOLUME_FADESTEP        (0x00000AAA)



int audio_overlay_bg_volume = AUDIO_OVERLAY_BG_VOLUME_MAX;

.
But I suspect that the spike has something to do with Hijack and/or Voladj logic. Maybe we can ask Mark Lord... But I'll see if I can find something... But I'm really impressed that all this is working this well already... Great stuff!
