REW help with Mytec Brooklyn DAC+

[Jsettoon]

I'm attempting to integrate two subwoofers with my 2ch audio system using REW. My issue is that when the JAVA driver is selected in the preferences page, I get an error message when trying to select my Brooklyn DAC+ as the output device. I can get test tones to play using the ASIO driver but then I can not use my UMIK-1 as an input device. I tried using asio4all but did not have any luck with that either (no audio test tones)

Error Message:

REW V5.20 Beta 29 running JRE 1.8.0_231 64-bit on Windows 10, en, windows-1252


Message:
javax.sound.sampled.LineUnavailableException: Speakers (Brooklyn DAC+) has no lines available supporting PCM_SIGNED 48000.0 Hz, 16 bit, stereo, 4 bytes/frame, little-endian

Any help would be much appreciated, I am a novice user of the REW software.

Most likely that error message means ( when trying to use Java ) that your Brooklyn DAC came only with an ASIO driver ( Java + ASIO4ALL usage demands that all USB device have a WDM driver also available for use by JAVA or ASIO4ALL ).

Scout out the specs for your dac unit to see what drivers are available for it ( you may need to contact the manufacturer ).

FYI, ASIO4ALL is flaky with certain nVideo graphics cards ( maybe all of them > honestly, I don't keep track ).

Successful ASIO4ALL usage demands that the device choices available (seen in the menu after clicking the wrench icon ) be lit up in electric blue ( iow; not dark, and certainly not sporting a big red X through the device name ).

Here's a useful document ( from Mytek ) worth reading.

Windows 10 - "No Sound" Issue! pdf

A quick glance shows your device has a WDM driver ( so my speculation on it's absence seems to be addressed ).

What sort of video card does your computer have ?

Thank you EarlK! I will try the steps in the Mytec document to see if I can get it to work. As far as the video card is concerned, I'm using an HP Spectra laptop with NVIDIA GeForce MX150.

Update - Problem solved! Windows 10 automatically sets the playback at 32 bit / 384 kHz for the Brooklyn DAC. Once the playback resolution is changed to a setting that REW is capable of using (16 bit / 192 kHz) the JAVA driver works properly. Thanks again EarlK for providing the Mytec document that had the answer!
