But, because of it's lightbuild structure OpenWrt does not come with audio support. Any USB Audio device supported by GNU/Linux should work with OpenWrt as well. ![]() If I'm completely wrong about this, and it isn't using the generic USB driver it seems to be installing when I plug it in, and would likely be completely incompatible with a generic USB 2.As long as you have the necessary hardware connected, OpenWrt can play audio, as can any other GNU/Linux distribution. There's a pretty good chance it wouldn't work, since all the DAC specs list 44 kHz as the USB input, but upgrading the USB audio driver to USB 2.0 is probably a good idea regardless, and if the DAC does in fact have a USB 2.0 port, it might let me upgrade the sample rate. I tried searching for one for download, but the sketchy one I found off of a third-party website didn't work at all, and just disabled all USB audio on my system (for this device and some other unrelated USB headphones I had) until I uninstalled it and swapped back to the original drivers. Ideally, I was hoping someone would have a legacy USB 2.0 driver for this, if it existed, or, failing that, a generic Windows 7 USB 2.0 audio driver I could replace the 1.0 driver with (either in 2.0 or 1.0 mode) to test out whether it would support a higher sampling input over USB. I assumed (but may be wrong), if I were to replace the USB 1.0 generic Windows audio driver with the generic USB 2.0 one, it should default to the legacy 1.0 connection if that's all the DAC supports, or the USB 2.0 if it has a 2.0 port (which would then let me select a higher quality audio input). Microsoft has since come out with USB 2.0 audio drivers for Windows 10, and Windows 7, but I'm not sure where to download the Windows 7 version, since the download I tried didn't really work. When I plug it in, it's installing the generic USB 1.0 audio driver that Windows 7 came with, and any USB 1.0 audio driver can't go above 48 kHz. I know the DAC (as stated) accepts audio input over s/PDIF at 192 kHz, and given that it was released in 2006, it almost certainly has a USB 2.0 connection (rather than a 1.0 plug, its likely impossible to tell for sure from looking at it since the connectors are identical, but USB 2.0 was released in 2000). I found that, but interpreted it slightly differently (but may be wrong). Hence, no matter what the incoming sample rate is, the UDAC upsamples to 192kHz. The attendant upsampling does not change the incoming word length (16bit/24bit) only the sample rate. The UDAC will upsample any incoming signal to 192 kHz including the USB input. The HeadRoom Ultra Desktop DAC accepts S/PDIF digital audio signals at standard rates & depths (44.1kHz, 48kHz, 96kHz, and 192kHz from 16 to 24 bit word depth) on both coax RCA and TOSLINK optical connections, and will decode 44.1/16 digital audio from your computer via a standard USB connection. HeadRoom has been pleased to be amongst the first audio manufacturers anywhere to incorporate highly advanced ESS Sabre D-A processor technology into our proprietary products. If it is capable of UAC1, it should at least allow for 24/96 ![]() If I Google " Headroom Ultra Desktop DAC" I find a 2006 product.Īt that time most USB DAC's where using a very simple receiver limited to 16 bit / 44.1/48 kHz only.Īs this is what Win shows as the max, I wonder if this DAC can do anything higher over the USB. I have no idea if it would, but am looking for a generic USB 2.0 driver I could use to test it with Headroom was bought over by which was bought over by, and I cannot find actual drivers for Headroom products anywhere!ĭoes anyone have or would be able to link me an updated USB audio driver that I could use to get USB 2.0 audio (192 kHz) over this device on Windows 7?Įdit: that second paragraph should read "The issue is, IF the DAC supports 192 Khz audio sampling over USB 2.0" I.e. ![]() The issue is, the DAC supports 192 Khz audio sampling over USB 2.0, but with the plug-and-play default driver, I can select a maximum audio quality of "16 bit, 48000 Hz (DVD Quality)" under Properties as the default driver is a USB 1.0 driver. When I plug it in to my computer (Windows 7), it automatically installs a generic USB 1.0 audio driver, which shows up in my playback devices as "Speakers USB Audio CODEC" and in device manager as "USB Audio CODEC".
