I’m working on our USB sound problem in Call Center with virtual machines and PCoIP and found this article that explains DPC and processes latency in Windows 7 and also 8. Of curse we found a solution that using 3.5 mm jack headset and Teradici audio driver. Sound quality is very good on this solution and Teradici driver can deliver HD sound via PCoIP to users. I tested many solution about this problem such as PCoIP tuning, virtual machine optimization and also VMware documents about Best Practices for Performance Tuning of Latency-Sensitive Workloads in vSphere VMs but nothing changed in my tests. I hope this problem will resolve on newer version of vSphere or VMware View. INTRODUCTION The list of brands for Windows computers, as well as the possible combination of hardware used in PCs is practically unlimited – this can lead to compatibility issues or undesired interaction of components. Also, many PC computers and their components are designed to deliver good performance for office applications or gaming. The demands placed on a computer used for music production are usually quite different than those for office or gaming computers. As a result, it is often necessary to tune off-the-shelf or self-built computer...
When we installed a new hardware or upgraded a driver, driver packages will be added to “%SystemRoot%System32\DriverStore”, After few time Driver Store folder size will grow and maybe it’s increased to above 2 GB or more, for cleaning and removing unneeded drivers, you can download “DriverStore Explorer” from this address: http://driverstoreexplorer.codeplex.com/ [quotes_and_tips]
A smart card, chip card, or integrated circuit card (ICC), is any pocket-sized card with embedded integrated circuits. A smart card ormicroprocessor cards contain volatile memory and microprocessor components. The card is made of plastic, generally polyvinyl chloride, but sometimes acrylonitrile butadiene styrene or polycarbonate. Smart cards may also provide strong security authentication for single sign-on (SSO) within large organizations. Smart cards supported by PCoIP but we need to configure somethings on virtual machines and PCoIP management console and then you can use it same as a USB drive. Also this feature supported by VMware, I’ve tested that on vSphere 5 platform. You must access to PCoIP MC, zero clients web access page and modify installed VMware view agent features. If you need to use smart card within virtual machine, you should remove PCoIP smart card feature from View Agent. After install VMware View Agent on your virtual machine, plug your security device to zero client and then logon on to MC. Select your device in discovery devices list and open view details page. If your security device detected by zero client, you can find that on “USB Devices”. You need to VID and PID values for insert to a new profile. Close view details page and go to “Profile” tab, you must create a new...
