Oh I see. I may try this driver on my desktop computer in a few weeks.

Actually I have already tried "lh hdastr.exe" in autoexec.bat but not loaded hda2.dll in system.ini. The computer works fine for several hours. I am not sure if the overheating was caused by hdastr.exe now.

Yes I simply add the line c:\windows\HDATSR.EXE to the autoexec.bat. I will try LOADHIGH later. Thank you for the reminder. An old usb-audio works fine now on my r61.

I decide to abandon the build-in sound card and use a usb audio device instead. Because the file hdatsr.exe seems to make the computer superheating. So please ignore the last reply as I can't retract or delete it. Thank you. @deomsh

@deomsh I followed the instructions on my laptop computer thinkpad r61, and tried almost every hdaicout.hda in this thread, but still can't hear a sound. HDAcfg.ini HDAICIN.TXT HDAICOUT.HDA HDALOG.TXT
