RC3 fails on Intel 915GAVL boards with Intel chipset

[Steve Wendt]

These files are the required files for:

RC3 release with debug uniaud32.sys driver.

Intel 915GAVL motherboard with internal audio enabled in BIOS. Returns HDA Intel with Realtek ALC880 from SYSINFO 6.2.5 with

IRQ OBh shared and FFAC0000h-FFAC3FFFh(Exc) reported.

However the Device Resources List primary report shows simply OS/2 Universal Audio and there is *NO* information for resources!

Audio is faintly there in the boot run to the desktop. However there is no audio for any desktop folder open or close, not does the system volume object work at all.

Mixer options to change volume and switches

It looks like it is actually playing sound, but the speaker is switched off.

This is a known issue with Intel HDA

Please try running the attached mixer.cmd, which turns speaker on, and sets max sound level.

Yoda .. I have tried your requested mixer .CMD file. It does nothing at all for the audio response here. I have learned one other thing that is a little different from the initial text posted above that was filed. The DEBUG version of the uniaud32.sys does permit you to go into the Desktop Settings, select the Window tab and "enable" Animation. After which you will get a faint audio sound for desktop folder opening and closing. The non-debug version of the RC3 uniaud32.sys seems to be at least a part of arbitrarily resetting the Windows Animation to "disabled" on boot up.

There is absolutely no change in audio response, levels or whatever when your suggested .CMD file is run. On bootup the Desktop Volume object has no effect on audio output level at all, nor speaker control at all. What you get for the weak audio on the back panel is what you get - period.

Have you tried using WarpVision - through UNIAUD API ?

There might be a chance that could work.

Please test with unaiud32.sys from ​http://download.smedley.info/uniaud32-1.9.2.zip - preferably with unaiud16.sys from 1.1.4RC5

Please test with a current build of Uniaud from ​http://svn.netlabs.org/uniaud and reopen or create a new ticket if the report is still valid.
