Why not use:

#!/bin/bash
if grep -q 23 /proc/asound/version; then
  echo "Version is 23"; exit 0
else
  echo "Version is NOT 23"; exit 1
fi
exit 1

This mean you don't need user input, the script does the test itself. The exit 0 means all is well and you can use the output in other scripts, exit anything other than 0 means an issue occured.

sorry...exit 0 means we need to go no further, would still like to know why exit doesn't work

I'd have though it would be exit 1, it means the file didn't output or the grep went wrong.

Glad you got the gold. You didn't need the user to input in your initial code though ;)
