Sound through mini DisplayPort on X210?

Did anyone get it working? I don't even see such a device in ALSA (inserting snd-hda-codec-hdmi module manually does nothing).

Re: Thinkpad T700 i7-10710 private project

I'm willing to pay big bucks for an upgraded X301 motherboard. Intel just released a "Pentium Silver N6005" that seems to fit the bill perfectly. 4 cores @ 10W TDP. Seems less expensive / easier than your T700... I mean, I don't think intel cares that much for the low end product lines. They are pr...

It doesn't respond when USB1/2 or USB3 devices are connected to it. The pins are clean, 5V is present, nothing pops up in dmesg when i plug anything in. What could be wrong with it and how could i figure out and fix it? A BIOS setting or hardware problem?

Re: X210 WWAN /mSATA port does mPCIE!

Interesting idea. However, that doesn't really help my use case - I wanted to combine the two slots to get an x2 device. If I can't even get devices to work properly at x1 in the first slot, there's no use in taking the clock lines and making the other one into an x1 port either... R But it does he...

Quick question: what are your thermal readings under the regular load? Are you using NVMe SSD or SATA 2.5"? I am using NVMe and it seems to be just on top of the CPU in x2100, so the front-left side of the laptop, under the palmrest, gets pretty hot, around 50-55 C for the CPU and up to 60 C for NV...

I doubt it. USB 3.x has extra differential pairs in it, separately from the regular D+/D- that are used in USB 2.0 (those are kept for "backwards compatibility").

Re: X210 miniPCIe eGPU?

Gen3 probably won't work over the USB cables they're using there, you'll need properly shielded cables. My Thunderbolt project works fine at Gen3 using the ADT-Link stuff, it's kind of expensive but it seems to be so for a good reason. This could work, for example: https://www.aliexpress.com/item/4...

Re: X210 miniPCIe eGPU?

Forcing the PCIe interface to Gen2 speed in BIOS setup made it work reliably.
The gaming performance isn't stellar though. I'm not sure whether a narrow bus, or [censored] drivers, or anything else is the reason though.

Make sure you turn off CLKREQ in the BIOS and ensure that pin 4 (CLKREQ) of the mini PCIE adapter is grounded, then it should work. Anything I've thrown at the bottom slot works, but admittedly I haven't done an EGPU

R
It isn't grounded, but does it even matter when CLKREQ is disabled in BIOS?

No, unfortunately you're correct that it doesn't work. If you turn on PCIE Hot Plug in the BIOS and look at a Linux boot log, you'll see that (1) a card IS detected but (2) it never exits the Link Training stage. I don't know why.
Have you tried limiting the port to Gen1 speed?
