Contents

In some cases, developers need more information for your hardware or ALSA software installation. To reduce their time to ask you for more details, please, provide this information.

Please, if you can, try to compile our latest code (especially for HDA drivers). Check "Hot" Daily Snapshots in Download page.

General

If you do not know if problem is in user space or in kernel driver, just describe problem and we will ask for more details.

Note: 

We have alsa-info.sh script providing information about your system and ALSA driver and library installation.

Note: 

We have alsa-compile.sh script to compile latest ALSA sources in an easy way. This script also does the kernel module management.


Driver

It is not a bad idea to send /proc/asound/card#/*regs* or *debug* or *codec* files (replace card# with problematic card).
