Introduction:
The Hermes audio server plays a crucial role in the audio processing and playback of various devices. However, users may encounter issues related to invalid sample rates when working with the Hermes audio server. This article delves into the common problem of invalid sample rates with the Hermes audio server and provides insights on how to address this issue effectively.
Understanding the Issue:
The issue of invalid sample rates with the Hermes audio server can manifest in various ways, such as very heavy distortion on transmit, errors during audio playback, or unsupported sample rates causing malfunctioning of audio devices. Users may encounter error messages like "Invalid sample rate when using ASIO driver #252" or "IOError: [Errno]" when trying to configure audio settings with the Hermes audio server.
Identifying Supported Sample Rates:
To determine the supported sample rates for devices connected to the Hermes audio server, one can refer to the test/system_info.py file in the PyAudio distribution. The section starting at line 49 provides insights on how to retrieve a list of supported sample rates for audio devices. By using this information, users can ensure that they are configuring the audio settings with compatible sample rates to avoid encountering errors related to invalid sample rates.
Troubleshooting Invalid Sample Rate Issues:
If users face issues like very heavy distortion on transmit or errors indicating an invalid sample rate, there are several steps they can take to troubleshoot and resolve the problem. One common scenario is when PyAudio does not support a specific sample rate, such as 16000 Hz, leading to errors during audio playback. In such cases, users can explore alternative sample rates that are supported by PyAudio to ensure smooth audio performance.
Another common issue is when the ASIO driver reports an invalid sample rate, causing disruptions in audio output. By checking the ASIO driver settings and adjusting the sample rate to a supported value, users can mitigate the problem of invalid sample rates with the Hermes audio server. Additionally, ensuring that the audio device is properly configured and updated can also help in resolving sample rate-related issues.
