Linux Audio Comparison
Of the challenges that GNU/Linux users face when choosing hardware components for any system is the sound card compatibility. ALSA, or officially known as Advanced Linux Sound Architecture, provides much of the audio and MIDI functionality to Linux users and is largely replacing OSS (Open Sound System). Today we are examining Linux audio performance in the gaming environment with a slew of various sound cards by examining their effect on frame-rate performance.
The contenders include Creative Labs Sound Blaster Audigy 2 Z3, Sound Blaster Audigy 2, Chaintech AV-710, Aureal Vortex (AU8820), and AC'97 integrated audio. Although we will have a few comments in regards to the subjective audio listening, we will be studying the CPU utilization with all of these sound cards and their effect on system performance when gaming; ultimately we are seeing the sound card's effect on the frame-rate performance.
