First of all, thanks so much for your work on it!
I tried to record audio from speaker, it return a array with correct shape, but all element is zero: [[0, 0], [0, 0], ...], and the data return immediately (not 5 second) . It is strange that it works well yesterday and record by pc's physical microphone (not loopback).
environment
PC: DELL G3 notebook computer; OS: win11; python3.7 and SoundCard v0.4.2
import soundcard as sc
OUTPUT_FILE_NAME = "out.wav" # file name.
SAMPLE_RATE = 16000 # [Hz]. sampling rate.
RECORD_SEC = 5 # [sec]. duration recording audio.
speaker = sc.default_speaker() # it is my speaker
print(speaker) # <Speaker 扬声器 (Realtek(R) Audio) (2 channels)>
micer = sc.get_microphone(id=str(speaker.name), include_loopback=True) # loopback record
with micer.recorder(samplerate=SAMPLE_RATE) as mic:
data = mic.record(numframes=SAMPLE_RATE * RECORD_SEC)
print(data) # data is a zero array, but data.shape is correct ???????

"""The other strangenesss is that it return valid audio array when play a music, but return [0] array when a few seconds after the music stops playing. The gif show it. (The RECORD_SEC change to 2 second)
