Talking Parrot responds static to audio

[lwcorp]

Describe the bug

dosbox-x-v2026.03.29 added #1824, i.e. Added SoundBlaster microphone input support (Windows WASAPI), but the parrot just responds in a static voice (as if you hear the parrot breathing air).

Steps to reproduce the behaviour

1. In dosbox-x.conf set recording source=microphone in the [sblaster] section
2. Run parrot.exe
3. Click Enter in the first screen
4. Choose a value in the second screen - see instructions below, if the first screen indeed has 130 you're supposed to enter 140
5. Talk to the parrot

Expected behavior

The parrot should repeat what you just said in a funny voice
