[Bug]: Python has no access to audio devices #20570

Open VladKolerts opened 2 weeks ago

VladKolerts commented 2 weeks ago

Problem description

Sox's rec and play working good, but from python modules can`t access to devices. I'm attempt to use sounddevice and pyaudio. Devices list is empty. 

import sounddevice as sd

sd.get_portaudio_version()
# (1246976, 'PortAudio V19.7.0-devel, revision 147dd722548358763a8b649b3e4b41dfffbcfbb6')
sd.query_devices()
# <empty responce>
import pyaudio
p = pyaudio.PyAudio()
p.get_device_count()
# 0
import speech_recognition as sr
sr.Microphone.list_microphone_names()
# []

What steps will reproduce the bug?

Install https://f-droid.org/packages/com.termux.api/

Grant microphone permission to Termux:API app in device settings.

Try to load module sles source.

Already done. You can see this steps at "What steps will reproduce the bug?" Without this, sox's rec and play will also not work.

Isn't portaudio using ALSA?

ALSA does not work on Termux.

no, ALSA don't installed. I describe the entire installation process in the block "What steps will reproduce the bug?"

Sound works in termux command line. My problem is sound devices are not visible from Python

sylirre commented 2 weeks ago

no, ALSA don't installed

That's not what I meant.

Sound works in termux command line.

Because command line tools made to work with Pulseaudio only. They won't attempt to query devices using ALSA.

My problem is sound devices are not visible from Python

Check what audio backend used by your libraries, especially portaudio which is a dependency for sounddevice and normally uses ALSA.

The issue you have is not a bug but a misconfiguration on your side.

Basically everything that does not use Pulseaudio or native OpenSLES won't be able to work with sound.
