10 years of PC4uMusic testings based on Gigabyte G1.Sniper A88X

Initially, the configuration of this motherboard, designed for gamers, was intended to serve as an exclusive showcase for the full potential of the flagship model of Japanese headphones. The idea was to present the Fostex FH900 for specially invited guests at a charming hotel in the center of Warsaw. This PC4uMusic  project was carried out at the individual request of the Polish representative of the Japanese manufacturer.

These headphones continue to receive very positive reviews. In them, any interference occurring in the PC power supply can be heard very clearly. Gigabyte's innovative design at the time, with a galvanically separated audio section, was the perfect solution to properly present these headphones.

 

The first PC4uMusic configurations with this design were conducted two years earlier in collaboration with the Polish representative of Gigabyte. An Intel-based motherboard G1.Sniper 5 was used for this purpose, but it didn't yet have sufficiently efficient drivers. Despite this, it made a beautiful appearance in its transparent Plexiglas enclosure at AmberExpo in Gdansk, and visitors were very positively surprised by the quality of the computer's music playback. 

 

A few meters away, Polish APS Coax studio monitors with a Norwegian 7 inch electroacoustic transducer SEAS Prestige Caaxial were also presented, but at that time at AmberExpo no PC4uMusic tests using them had yet been carried out. However, these active near-field studio monitors later became the reference for PC4uMusic. configurations. Their highly successful design, with a coaxial driver in a sealed enclosure, plays a significant role in this.

An even more important reference over the years is the Windows Audio Session Application Programming Interface settings in the freely available AIMP program. It can be used to convert digital signals to analog signals with a precision of 32 bit float/192 kHz. This program operates with exceptional accuracy, which positively impacts the quality of music playback. Its latest version is still in development, but already very promising and, as always, stable.

The driver for the motherboard's sound processor Realtek® ALC898 is crucial. Subsequent versions have enabled even more accurate music playback, and the latest version, version 6.0.9885.1, released on September 9, 2025, also works perfectly for taking advantage of Intel HD Audio capabilities. An important function is the ability to manually configure the signal according to the speaker layout - Room Corretion. The correct settings can be made without the help of a microphone, but they are not easy to understand. 

 

An alternative is the Windows system driver for the sound processor, but it can only be used with a microphone. This function is available for analog and digital signal outputs. Driver 10.0.19041.3636 for Realtek is from October 19, 2023, but works fine. Driver 10.0.1.41 for HDMI via built-in AMD graphics is from May 26, 2025.

 

The Microsoft driver for Realtek® ALC898 also allows analog connection of a very practical surround sound speaker system. This 4-speaker configuration is based on the old Dolby MP Matrix standard. This connection will be interesting for home use to play recordings using the Eclipsa Audio format, which has already become the standard for posting surround sound videos on YouTube.

 

Currently, tests are being conducted with a free South Korean program to play multimedia streams. It allows playback at up to 240x144 resolution and full audio quality, which is important when bandwidth limitations sometimes arise when connecting to a remote server. There are also wide possibilities of signal configuration for various speaker sets and further development in this area will be strongly focused on utilizing the potential of Eclipsa Audio.

Benjamin's psychoacoustic lab  is constantly testing and implementing possibilities for optimal music playback using new technical solutions with the computing potential of computers and open structures. PC4uMusicis the main project.
