I can give a simplified explanation to some of your issues. First, Intel-HDA is a bus designed by Intel for motherboard manufacturers to use different audio codecs based on usage models for each system. One Intel chipset (X58 in your example) can have literally 100 different audio chip combinations. Different audio codecs (in your case a realtek codec) behave differently. Some have volume controls for each plug, others have it just for each channel (which can be independently mapped to different plugs).
The "Front" volume control on your system, even though the plug is on the back panel, is for Front speakers in a surround sound configuration (either 5.1 or 7.1 surround depending on the number of jacks your system has). As to the mute/unmute issue, that sounds like a possible bug, but could also be a configuration issue where your board isn't directly supported but there is a configuration "model" in the driver that may work better than auto. Try downloading alsa-info.sh from http://alsa-project.org, run it with --no-upload, and post the results on this thread (please don't only reply to me, as my alsa support time is very limited at the moment). -- Tobin Davis I put up my thumb... and it blotted out the planet Earth. -- Neil Armstrong On Wed, 2010-04-07 at 16:03 -0700, Mark Knecht wrote: > Hi, > I don't know if others are seeing this with the Intel-hda driver > set but my wife's new Intel X58 chipset based machine is a bit weird > with the 1.0.21 drivers from the 2.6.33 kernel.
