Nerdy Mind, Windows 10

Windows 10, VIA HD Audio, No Speaker Fill, 5.1 Fix, Drivers.

Leave a comment

Well, windows 10 arrives and we wait for audio drivers. The built in ones only provide 5.1 audio when using Edge/IE. So you’ve only got 2 channel sound (no speaker fill) and when you open the sound properties you get an enhancements warning.

These drivers worked for me (VIA Vinyl 2021 HD) and I guess for most VIA audio codecs.

Nothing special to do, just install and enjoy. One thing I did notice is the HD Vdeck app does not open.

[Update]
the HD Vdeck app now opens under TH-2 build 10532 of windows

Centos 6 / 7 Openvpn forwarding not working

Leave a comment

Seems Centos (thus RH) have changed the way things work slightly. Especially if you have multiple interfaces (NIC’s).

If your having problems with VPN not forwarding correctly, or your openVPN stopped working since updating from Centos 5, then this will most likely be what your looking for.

nano /etc/sysctl.conf

change

net.ipv4.conf.default.rp_filter = 1

to

net.ipv4.conf.default.rp_filter = 2

now reboot and enjoy.

Install Bitdefender Anti-Virus on Windows 10 technical preview.

Leave a comment

If your having poroblems installing Bitdefender Anti Virus on Windows 10 technical preview, try this (works for me).

Download the Bitdefender installer from Bitdefender website. If you bought it online then use the link in your purchase email.

Place the file somewhere easy to get to, like c:\temp.

Now use the compression program of your choice to unpack the contents of the file. I use 7-zip, so right click the downloaded file and select ‘7-zip’ -> ‘Extract to’.

now open a command prompt as administrator and navigate to c:\temp

cd c:\temp
setupdownloader.exe /silent

The install is silent, there will be no on-screen progress or results. Just wait a minute or two (depending on your internet speed) while the program downloads and installs. Eventually you will see the Bitdefender program appear in the system tray.

Enjoy

Ubuntu 14.04 (Linux 64 bit) – No network, no USB 3 / USB 2

9 Comments

This mainly applies to 970 chipset mainboards, so your mileage may vary.

Symptom, no USB 3 , or Network, or USB 2 using Ubutnu 14.04 (actually from 12.04 up) 64 bit editions. As this is a kernel problem this should affect most 64 bit linux distros, not just Ubuntu.

There seems to be a problem with all recent 64 bit linux distros and 970 chipset mainboards.

There are 3 options.

1) Use a 32 bit distro.

2) In your BIOS enable IOMMU. This will fix your network and USB 2. You probably wont have USB 3 though 🙁

3) Enable IOMMU in BIOS and add iommu=soft to your grub config. This gets rid of the stream of warnings you get at boot with IOMMU enabled in BIOS. USBB 3 should work too.

sudo nano /etc/default/grub

Change the line

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

to:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash iommu=soft"

Then do

sudo update-grub

and reboot.

This should make the USB 2 and 3 work as well as networking.

Let me know what chipsets/mainboards this helped you with.

[updated]
Changed option 3 as noted by Anthony Barnett. Many hanks for the feedback Anthony.
