Play waveform through speaker doesn't work on Mac #66

Hi. While trying to annotate recordings with DAS, I can't hear the sound when I press the 'E' key. The following errors appeared on the terminal window. Seemingly, version of portaudio (v 19.6.0) or python-sounddevice (v 0.4.6) installed from conda is the source of problem. My environment is Macbook Air with M1 chip and MacOS Sonoma 14.2. Everything else, including exporting annotations, training, and prediction processes, has worked fine.

Hi, yes, sound playback is always a bit of an issue. We now use simpleaudio as a fallback, which should work on arm Macs. Reinstalling DAS should fix the problem.

Now that the audio playback problem is fixed. Thank you so much!
