HDMI cable quality impacts sound
HDMI cables are renowned for their ability to streamline audiovisual setups by carrying both audio and video signals in digital form through a single cable. This simplifies the setup of home theatres by reducing the number of cables needed and ensuring synchronization between audio and video outputs.
While HDMI cables are designed to transfer audio in its purest digital form, the quality of the cable can impact the sound quality. Cheaper cables may use smaller conductor sizes, which can lead to signal dropouts or similar issues, especially over longer distances or in high-interference environments. Additionally, low-quality cables may be less flexible and more prone to breakage, which can also affect sound quality.
Some users have reported hearing subtle differences in sound quality when using different HDMI cables. While the impact may not be significant, some have noticed small improvements or reductions in soundstaging, dynamics, or the presence of random clicks and pops when using lower-quality cables.
To ensure optimal sound quality when using HDMI cables, it is recommended to choose high-quality, high-speed cables that are compatible with your equipment and capable of transmitting high-bandwidth audio formats. Opting for cables with larger conductor sizes, such as 28AWG or 24AWG, can also help reduce signal loss over longer distances.

HDMI cable speed and testing
HDMI cables are a standard way of transmitting high-quality video and audio between devices. However, not all HDMI cables are the same, and their speed and bandwidth can vary depending on their quality, length, and type. Therefore, it is essential to know how to test HDMI cable speed to ensure optimal performance.
There are various methods for testing HDMI cable speed. One accurate way is to use a cable tester, a device that measures the bandwidth and signal integrity of HDMI cables. Cable testers can detect faults or impedance mismatches affecting transmission quality and can generate test patterns and EDID data to simulate different conditions and resolutions. Cable testers come in various forms, such as handheld devices, PC software, or hardware modules that plug into your devices. Examples of popular cable testers include the Murideo Fresco Six-G, HDFury Vertex 2, and Extron AV test pattern generator.
Another method for testing HDMI cable speed is to use benchmark or stress test software, which can be found online. These tests push the cable's bandwidth to its limits by transmitting various video and audio formats at different resolutions and frame rates. Examples of popular HDMI testing software include SpectraCal CalMAN, DVDO AVLab TPG, and Murideo SIX-G.
Additionally, you can check HDMI diagnostics by going into the settings of your device. On some devices, you can hover over programmes, then press 11111 to access the HDMI diagnostics, which will show you the current bit depth, colour space, chroma, etc.
When testing HDMI cable speed, it is also important to consider the video format and settings of your devices and TV. Certain video formats and settings, such as 4:2:2 chroma subsampling, HDR, deep colour, or motion interpolation, require more bandwidth and can affect signal quality. Adjusting these settings can optimise performance and compatibility with your HDMI cable.
Finally, visual inspection and understanding the cable's specifications can also help determine if an HDMI cable is high-speed. Cable labelling and packaging can provide information about the cable's designation and bandwidth capabilities. For example, a standard HDMI cable supports up to 1080p, while a premium high-speed HDMI cable supports 4K at 60 Hz with HDR (up to 18 Gbps).
