- | Two quick questions about audio for one of our programmers.

- | 1. How do you set the default audio gain level in hardware on
- | a 35 or indigo? (nvram parameter?)
-
- "nvram volume xx" (xx is 0-255) from irix, or "setenv volume xx"
- in the PROM monitor.
-
- | 2. Exactly how do the gain slots (0-255) map to real world db values?
- | (linear relationship?)
-
- Can't help on that one, perhaps one of the audio guys can help.
-
- | And, I guess, a question from me. I'm assuming 8-bit samples.
- | Is this correct?
-
- 8 bit samples for what? The hardware uses 16 bit samples for
- the digital audio.
