Run alsamixer and see if there is a "PC Speaker" control there; unmute it and set the volume appropriately. The system startup scripts are responsible for saving the mixer state on shutdown and restoring it at startup; they are distribution-specific. > Furthermore: I see that many onboard chips (realtek, intel etc.) > use the i8x0-driver.

All current onboard sound implementations consist of two parts: - AC'97 controller (included in the chipset) - provides a digital AC-link interface; - AC'97 codec - attaches to the AC-link interface and provides analog inputs and outputs. snd-intel8x0 is a driver for Intel-compatible AC'97 _controllers_ (besides Intel chips, it can also work with some SiS and nVidia chips, which have a compatible register layout). It should be able to work with any AC'97 codec attached to such a controller. The snd-ac97 module contains common routines for working with AC'97 codecs (including quirks specific to some codec chips). > If not: Can some of the cards do hardware-mixing and/or is a > kernel-level software-mixing solution planned sooner or later (for > alsa post-1.0)? Some AC'97 controllers can really do (limited) hardware mixing - e.g. VIA VT8233/8235 (4 channels). ------------------------------------------------------- This SF.net email is sponsored by: IBM Linux Tutorials.
