Need help getting High Definition Audio working on Windows 98 on my Thinkpad T420

[deomsh]

I am afraid something went wrong during the 'EDIT'. Should work again.

Here you are, it seems to start a little quicker after that, and the volume/ gain is lower.  volume adjustments  in  waveset seem to  be more linear now and not chopping on and off, but the max volume seems to be lower than  before.

Thanks!

Judged to the response of this GET-verb in HDAICIN.TXT you really did the test with headphones unplugged:

sent $019F0900; got $7FFFFFFF ticks=0000000A

Sources on this verb are not really clear however.

I hope next version of HDAICOUT.HDA will be the final one. Volume is set back to maximum (0x4A). In previous version I gave you the default state (0x3C).

What is left: only a few SET verbs:

Hi! sorry about the delay was busy the   last few  days, I just copied  the new file over, and it sadly doesnt want to boot  into Windows anymore.

Its  no problem ill just use the rev2 file, it works great.

 

Thanks again for  all your help! You  are doing great things for the Retro Computing community!

Thanks.

Maybe first line is too long.

What if you delete all seven lines starting with ';;' ?

BTW: with the verb '$0103B04A;AC_VERB_SET_AMP_GAIN_MUTE;max_vol(default=3C)' I'd try to give you your max volume back as in debug-version!
