This package contains the software that enables the Intel HD ALC260 Sound Chip in the listed workstation models running the listed operating systems. NOTE: The following list contains known issues for this software: - To adjust and unmute system volume, use 'alsamixer'. Using the default desktop volume control provided with the operating system does not enable control of the internal speaker. - A ''Depmod error'' may occur when installing the ALSA-driver. This error does not effect sound performance. This issue is planned to be fixed in the next release of the software.
