sounddevice rec stop playing when silence detected

[Christhian16]

Hello,

I'm currently using sounddevice to record audio from my speaker output using this code.

import sounddevice as REC
from scipy.io import wavfile
SAMPLE_RATE = 44100
SECONDS = 20
MONO    = 1
STEREO  = 2
REC.default.device = 12
REC.default.channels = 2,0
recording = REC.rec( int(SECONDS * SAMPLE_RATE), samplerate = SAMPLE_RATE, channels = 2)
REC.wait()
wavfile.write('recording.wav', SAMPLE_RATE, recording)

Normally, it should record for 20 seconds but instead if stop at silence before the 20 seconds had finished.
So, for the recorded audio, the length is actually 20 seconds but I get 7 seconds of audio because after 7 seconds there was a silence.

Can you please help me with this issue?

Thank you in advance for your reply.

I don't understand.
Does this still happen?
If yes, can you please provide more information, including the resulting WAV file?
