Native (WDM) HD Audio driver for Windows 98se/Me

Also sometimes the order in which the verbs are sent can matter. Some Realtek codecs like the ALC272 need to have a format set before the node is powered up, and some other codecs need to be powered up before they will respond to setting the format.

Interesting, noted.

I looked into the thread of  @Dave-H but two times no issue in case of ALC272 ( @Danielx and @isolar ) . At least not in case of HDA2.DLL. Not fully sure if  Verbinterface=$1 in both cases.

Confirmed I always set power on first, then stream format later after path is connected. This works on ALC272 with latest HDA2.DLL. Works with Verbinterface=$1 and $0 - very fast with $0 (IC mode)!

Actually the speaker on these devices is interesting as it shows the connection type from F1C get verb as a 'ATAPI Internal' - 3h rather than an 'Other Analog' - 7h as most laptops do. I wonder if this has something to do with it? However the log shows it definitely is identified as a speaker so maybe not the problem, and back to the power node i'm thinking that the WDM driver routes through the mixer node 0E (?) so possible your original thinking of powering on this node ($14) might do the trick.
