Post subject:  Question about StarTech audio interface/setup

I recently bought an RS-HFIQ setup and am trying to get it installed according to the guide, but am encountering an issue that I want to ask about.

I am using a Lenovo Thinkcentre M92P with a fresh installation of Windows 10. The PC has multiple USB 3.0 ports.

Windows 10 shows this as a "USB Advanced Audio Interface" with SPDIF.

When I plug in the StarTech audio interface and configure it according to the Quick Start guide, the best quality I can get on the microphone setting is 1 channel, 16-bit, 48000Hz. I do not ever see any options for 2 channels or 24-bit anything on the microphone control panel.

On the speaker control panel, I see the built-in speaker and built-in headphone jack for the PC, and an SP-DIF Interface for the StarTech adapter -- no speaker setting. I can configure it for 2 channel, 24-bit, 96000Hz as recommended, but I am not sure that this is what I should be setting -- is this correct for Win10? On the example screen cap in the Quick Start guide it shows both a Speaker and SP-DIF setting, but that also appears to be captured from Win7 and not Win10. Should I expect to see that setting in Win10? If I should expect to see it, this combined with the apparent limitation in the microphone setup seems to indicate that I may have a defective audio adapter OR the driver is not correct/up-to-date. Checking StarTech's web site does not lead me to a driver download of any kind, and I don't find one on the RS-HFIQ wiki page either.

Any input here would be appreciated. I've actually tried this on multiple PCs, through the USB 3.0 hub as well as directly connected to a USB 3.0 port (and USB 2.0 as well, on an older machine) and multiple fresh installs of Windows 10 with similar results each time. I have not tried a Windows 7 build yet, but I am considering it. I would like to get this thing on the air but at this point I'm concerned that either the hardware is no good or there's a driver or other configuration issue in the way.

Thanks and 73

Hi Tony,

If your StarTech says 'Rev B' on the sticker on the back, it needs new FW to get 96 kHz, 24 bit, Stereo input.

If you go to this link:


They have excellent instructions on how to install the new FW.

It took us a while to get it all sorted out but, believe it or not, StarTech released the new version on FW specifically to support HobbyPCB!

Thank you for your response. My card is a Rev B but apparently was at an older firmware version (8808). The update to 8810 did indeed give me the ability to do the 2-channel, 24-bit, 96000Hz settings on both TX and RX. Wish I had asked this before spending money on a new-to-me PC, as I thought it was a USB chipset issue (read a comment you made to another forum user who had a similar-sounding issue), but it's not a big deal as I got a good deal on a faster machine with USB 3.0 (my other ThinkCentres were older with USB 2.0 only).

However, I still get only the SPDIF device as the input device in the sound control panel. I assume this will work?

Thanks again,

Yes even with the new firmware there is a slight difference in the input and output nomenclatures but as far as I could tell everything works just like it should.
