Since we are talking about linux host, i'd use NetJACK. Transfers audio via UDP, combined with enormous localhost bandwidth there should be no big problems in getting it work. <div class="gmail_quote">On Oct 16, 2015 6:29 PM, "Sinisa Tkalec" <<a href="mailto:xslisx@hotmail.com">xslisx@hotmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">VBCABLE, The virtual audio cable works fine for steam streaming on windows7.

USB to in-line onboard sound card to the amplifier results in really bad sound quality. Also updating my setup is not possible for me right now since a new motherboard + 6core CPU is not in the budget. I hope that i will find a workaround. Thanks a lot again for the support since right now the basic functions are working fine.

Unfortunately, X58 is pretty old and there's not likely to be much interest from Intel or the development community to figure out what's wrong. You should also factor in that your Westmere processor isn't going to have the same virtualization performance as a modern Haswell, which makes the problem even less interesting. If you only need audio out, maybe you can pull it off the HDMI or DVI port of the GTX680 since you're assigning it anyway. Maybe your monitor already has an analog or SPDIF output. Are there any PCIe slots left on the board? A cheap plugin sound card may be an option.
