Subject: Digital sound card conventions
Date: Fri, 3 Jan 2003 20:44:04 +0100 [thread overview]
Message-ID: <200301032044.04034.torger@ludd.luth.se> (raw)
I'm doing a maintenance update on the rme96 driver, and I wonder if
there are any conventions to follow in the driver concerning digital
sound cards.
The specific questions are how to handle sample rates and sound formats
on the input.
The sound card supports several sample rates and formats. What should
happen if the user tries to open the input with 48000 kHz ADAT, but the
format is actually 44100 kHz and SPDIF? I can allow it if I want to,
the user will get data, but at 48000 kHz of course.
What should happen when there is no input signal at all? The hardware
supports opening the input, but should I do so in the driver?
The signal can of course change in runtime as well...
I'm thinking of allowing it all, but I don't know if that is the right
way to go.
