Yep, it does not work without the USB Recorder Pro. It's in the thread if you search for it.
NOTE 2 and HTC One X Plus owners.... I found after searching that this phone supports USB-DAC with the TouchWiz ROM. Do any of you know if the AOSP ROM's like AOKP and CyanogenMod also support USB-DAC for this phone (without a patch)?
I'm getting frustrated with the lack of support on the Galaxy S3 AOSP ROM's.
can you give me a link to a HDD cable that fits your description. i tried one of the dual USB cables and it may have been powering my dac/amp (not sure if i could figure out how to tell), but the charge idiciator showed it was not charging my T-Mo S3.
