Audio

All HP workstations come with built-in audio hardware. The audio hardware is supported by the
Advanced Linux Sound Architecture
The audio hardware provides basic playback and recording features. The ability to simultaneously
play audio from multiple sources, such as applications and CDs, is provided in the ALSA driver that
provides audio mixing. The performance of software audio mixing and playback is greatly improved in
ALSA version 1.0.13 and later.
After the driver is installed, the optional NVIDIA and AMD graphics cards that are supported in HP
workstations also provide audio functionality over HDMI. The signal can be passed through the
DisplayPort connector to a monitor with audio capabilities. The vendor driver must be installed. Such
