In Device Manager -> Sound, video and games controllers -> Realtek high definition audio -> Properties -> Details tab
I have both
HDAUDIO\FUNC_01&VEN_10EC&DEV_0221&SUBSYS_103C3397&REV_1000
HDAUDIO\FUNC_01&VEN_10EC&DEV_0221&SUBSYS_103C3397
Does this give you any useful information?
YES!
according to the drp.su site, HWID "HDAUDIO\FUNC_01&VEN_10EC&DEV_0221&SUBSYS_103C3397" is listed in the HDAHPBPC.inf & HDXHPBPC.INF files. Those INF files seem to not only install the SRS DLL files but also register a bunch of SRS related reg entries in the [SRSInstallerSRS_PS.AddReg] section of those INF files; I do not have the [SRSInstallerSRS_PS.AddReg] section in the HDXCPC.inf and HDXCPCold.inf files since the HWID that I have on my HP computer is listed in a different INF file.
I found an SRS Premium Sound for HP app listed in the "Software - Multimedia" section of the HP Compaq Elite 8300 SFF (Small Form Factor) downloads page and choosing Windows 7 x64 as the operating system on the HP support site [packaged in the sp57738.exe file]. this version of SRS Premium Sound app can actually be installed on virtually any HP/Compaq computer, even on my HP pavilion m8417c computer - the following below are the screenshots of having this version of SRS Premium Sound installed on the Hp m8417c.
notice in this screenshot there's an SRS_PremiumSound_amd64.sys driver file in the \Windows\system32\drivers folder and Device Manager lists SRS Premium Sound in the Sound, video and game controllers section.
