New, and impressed, user of UnRaid here. I've worked out most of the problems I've encountered but there are two I haven't been able to solve so I hope you can help.

 

1) UnRaid doesn't pass through my integrated audio or the back button on my mouse in VMs (Realtek ALC1150 in ASRock Z97 Extreme4 motherboard). The back button works fine in the UnRaid display.

 

System Devices / PCI Devices (No IOMMU Groups Available) shows:
[8086:8ca0]    00:1b.0 Audio device: Intel Corporation 9 Series Chipset Family HD Audio Controller

 

so it's pretty standard (if old) stuff and I can't see what I'm missing.

 

2) My PC has 2.5Gb ethernet on board and to save buying a new router I thought I'd get a USB 2.5Gb network adaptor and bridge the connection in UnRaid so that the connection between the two computers would be faster than the regular 1Gb network, which doesn't need it. It looks right in UnRaid but doesn't work. The only thing I can think of is that I'm just using a normal Cat 6 cable but from what I know it shouldn't need a crossover.

Any ideas?

According to the diags, VT-d is disabled, check the BIOS.

You must set a static IP for that NIC, typically, in a different subnet, and leave the gateway blank.

 

Thanks for your quick reply and suggestions, sorry mine is slow, I couldn't check the VT setting as I was running a parity check at the time.

 

Once it had finished I went into the BIOS and found Intel Virtualisation Technology enabled and Intel VT-x Tecnology supported so I had thought it was set up correctly but going through all the settings I found VT-d under Chipset so it is now enabled and I see the audio controller in 'Edit'. However the back button still doesn't work. UnRaid sees the mouse in the VM settings but if I enable it, it doesn't work at all in the Windows VM. I have to unplug and re-plug it so that Windows recognises it. It works if I don't select it but still no back button.

 

Regarding the ethernet pass-through, both computers have static IP addresses set in my router. Having connected it up I checked that my Windows computer is set to DHCP and did an 'ipconfig /release' and 'ipconfig /renew' but nothing happened, it wouldn't renew. I'm unfamiliar with Linux and UnRaid so could you talk me through setting a static IP for the second NIC and changing the subnet? Or would it be easier to just buy a 2.5Gb switch to connect them?

Isn't that for the gigabit NICs? I was talking about the 2.5GbE NICs.

Yes, that's right, UnRaid's on-board Gigabit NIC faces the router, I want to connect the 2.5Gb USB NIC to the on-board 2.5Gb NIC on my PC, passing through the network connection.

For that, you typically use a direct connection, assuming the desktop also has a seconds NIC connected to the switch, and if it doesn't, you would need a 2.5GbE switch.

 

 

 

Thank you, that was helpful but I still can't get it to work. I managed to get the computers talking to each-other via 2.5Gbe but UnRaid didn't bridge the connection - i.e. I want UnRaid to pass the internet connection from its on-board 1Gbe socket to the 2.5Gbe adaptor and out to my PC. The video shows using one network port going to the switch as usual and the other linking the computers directly but I only have the one 2.5Gbe socket on my PC, hence the need for the bridge.

 

I then thought the easiest thing to do would be to just buy a 2.5Gbe switch so I tried to make UnRaid use the new USB 2.5Gbe adaptor to connect to the existing switch but couldn't work out how to do that as it still wants to use eth0.

 

Can UnRaid pass the ethernet connection to the second adaptor as I hoped or do I need to buy another network adaptor for my PC so that I connect each computer to the switch then connect the computers directly via the 2.5Gbe adaptors as in the video?

You don't bridge, they are used as separate connections, use the 2.5GbE IP when you want to use that for faster file transfers

Ah-ha, with the aid of that video and ChatGPT I've got it working!

 

In Network Settings I set Enable Bridging to yes, added both adaptors to 'Bridging members of br0:', set my normal static address, pressed 'Done', restarted the array and now I have a single network cable connecting the two computers and one from the UnRaid server to the switch, with UnRaid passing the Internet connection through to my PC while giving me fast file transfers between the two computers, exactly as I'd hoped.

 

It looks like the problem was not adding the second adaptor to 'Bridging members of br0:' - obvious in retrospect but he didn't do that in the video and for some reason it wasn't working at first.

 

Thank you so much for your help, I really appreciate it and as I become more familiar with UnRaid I hope to pass on my experience to others.
