sampleRate not being used for the Audio Track

[KrishnaPG]

Describe the bug

What is happening

I am using useTrackToggle with custom sampleRate as below on the browser side, but the audio sample received on the node.js server side is not changing, and always 48Khz:

  (props) => {
    const { buttonProps, enabled } = useTrackToggle({
      source: Track.Source.Microphone,
      captureOptions: {
        autoGainControl: false,
        channelCount: 1,
        echoCancellation: true,
        noiseSuppression: true,
        voiceIsolation: true,
        sampleRate: 16000, // Gemini Audio input needs 16Khz, LE, raw PCM
      },
      onDeviceError: (error) => props.onDeviceError?.({ source: Track.Source.Microphone, error }),
    });
    return (
      <Button
        {...buttonProps}
        Icon={enabled ? Mic : MicOff}
        title={enabled ? "Mic is ON" : "Mic is Off"}
        className={enabled ? styles.on : styles.off}
      />
    );
  },

What is expected

When the sampleRate is set on the browser side react component, the server side should receive audio samples at the set sampleRate

Reproduction

Use the above code in the react for creating a custom MIC button and monitor the audio frame sample Rate received on the server side.
