While i was browsing the dell xps tower desktop drivers i noticed the audio driver description for it mentioning realtek ALC3861, however all high end boards are using ALC1220 so is there some high end audio codecs from realtek that are exclusive to corporate OEMs or dells marketing just being silly ?

Its possible, hard to say in this specifically. OEMs also sometimes modify chips to tune functionality to a specific product (think needing OEM video drivers instead of just getting them from AMD/Intel/Nvidia in certain laptops). When this happens they may distribute drivers they package themselves with a modified internal name. Or strike a deal with the IC manufacturer for x amount of specific custom chips.


It could also, just be a typo.

it's not a typo.

Dell uses Realtek ALC3861 audio chips (a customized chip for Dell) not only on XPS series but also on certain Inspiron and Alienware Area-51 series as well as I see ALC3861 drivers for other Dell series (examples of ALC3861 drivers are here, here & here).

Simple, it's a two, or maybe a four channel audio codec and most likely a low power part, rather than a 5.1 or 7.1-channel desktop part.
Realtek has a myriad of products and as pointed out above, many are custom made for their partners.
Have you ever seen an ALC5611?
Or an ALC5629?

Find your true id.
Go to device manager.
find realtek audio.
open advanced properties, details tab.
find the hardware id.
e.g.HDAUDIO\FUNC_01&VEN_10EC&DEV_0225&SUBSYS_10280884
In this case the chip is a 225 (the dev_ part). Your answer lies there.
The example chip was labeled as alc3253 by dell.

So you'r saying the alc3253 labeled by dell is in fact an alc225 in the hardware id ?
