Hi! I understand you're having an issue with the Automatic Call Recorder app (version 6.60.4-sam) where currently you cannot hear any audio. Let me help you get this sorted out.

To start, could you let me know a bit more? For example:
- Is the problem that you cannot hear audio playback of recordings within the app? Or is it that calls aren’t recording any sound at all?
- Are you using the app on your Windows device through some emulator, or on an Android phone?
- Have you noticed whether this affects all calls or only certain calls?
- Has the app been working fine previously, or is this a fresh install?

With those details, I can tailor the guidance better, but in the meantime, here are some initial general steps to try:

1. Check App Permissions:
Ensure the app has permission to access your microphone and storage (if used on Android). Without mic access, it cannot record audio.

2. Restart Your Device:
Sometimes a simple restart refreshes system resources and can resolve audio glitches.

3. Check Audio Settings in the App:
Open Automatic Call Recorder and check if there are any in-app audio settings or audio source options. Sometimes changing the audio source from “Default” to “Mic” or “Voice Call” can help.

4. Update or Reinstall:
If possible, check for app updates or reinstall the app. There might be a bug in the current install affecting audio.

5. Test with Different Calls:
Try recording different types of calls (mobile, VoIP) to see if the issue persists across all.

6. Check System Volume & Audio Devices:
Make sure your system’s audio is not muted. If using external audio devices, verify they are properly connected.

Once I have more information about your setup and exact problem, I can provide more detailed steps or advanced troubleshooting.

Are you using an Android phone or trying to run the app on Windows? And is the problem with recording calls or with playback of recorded files?
