I am trying to develop software that record sound from mic input. And I am using Docker to develop and run in container, but from container I cannot access to mic device.
Environments:

• docker:26.0.0.0
• python:3.12.3
• sounddevice:0.4.6
• LinuxMint(HostOS)

and here’s my dockerfile and compose.yml

###
# Base
FROM python:3.12-slim as base

# Install dependencies
RUN apt-get update 
  &&  apt-get install -y --no-install-recommends curl gcc g++ pkg-config libssl-dev libasound-dev portaudio19-dev pulseaudio socat alsa-utils 
  && apt-get clean 
  && rm -rf /var/lib/apt/lists/*


# Create a app user and working directory
ENV APP_HOME=/app
RUN useradd -ms /bin/bash app 
    && mkdir -p $APP_HOME 
    && chown -R app:app $APP_HOME

# Switch to the app user and working directory
USER app
WORKDIR $APP_HOME

# Copy the requirements file
COPY --chown=app:app requirements.txt .
RUN pip install --no-cache-dir --upgrade -r requirements.txt

COPY --chown=app:app . .

services:
  app:
    build:
      context: .
      target: base
    command: python3 -u -m observer
    volumes:
      - ./:/app
      - ~/.config/pulse:/root/.config/pulse
    devices:
      - "/dev/snd:/dev/snd"

I tried to add -device:/dev/snd:/dev/snd but it did not work for me.
