Fixing USB audio controller (CM108) for headphones

Cheap USB audio controller Recently, I bought a cheap USB audio controller because my motherboard's built-in microphone input was dead. However, there were some problems with the stereo output. It seems to work well when it was connected to a pair of powered speakers, but there was only noise when connected directly to my earphones. When I measured the output voltage, it shows a 2 - 4 V bias voltage which is unusual because it should not have any bias voltages and normally 0 V when no audio. When plugged into my Linux machine, lsusb shows the following: $ lsusb | grep -i audio Bus 005 Device 003: ID 0d8c:013c C-Media Electronics, Inc. CM108 Audio Controller So, with a little googling for CM108, I found that the datasheet at  http://www.halicky.sk/om3cph/sb/CM108_DataSheet_v1.6.pdf and also Kevin Custer's site about modifying it http://www.repeater-builder.com/projects/fob/startech-fob.html When I opened up the device and compare it with Kevin Custer's photos,...

Missing xterm on Linux Mint when installing Juniper Network Connect

I was trying to connect to company SSL VPN that uses Juniper Network Connect on Linux Mint 17 64-bit. However, the network connect dialog keeps shutting down after launch for  a few seconds. I've followed their support documentation at http://kb.juniper.net/InfoCenter/index?page=content&id=KB25230 but it was still not working. After a bit digging around, I found the log fail at ~/.juniper_networks/network_connect/installnc.log shows missing xterm. After installing xterm with sudo apt-get install xterm, I can finally connect successfully to the VPN.
