Can't record from a digital connection
When capturing audio data from a CD or MD into your computer, is the digital
input switch "on"?
Turn on the digital input switch.
Does the sample rate of your software match the sample rate of the digital
audio device connected to the digital in connector?
Set the sample rate to the same setting.
If you change the UA-25's sample rate, you must disconnect the USB cable that connects
the UA-25 to your computer, and then re-connect the USB cable in order for the new
setting to take effect.
Recording produces a silent file
Did you specify the correct audio data input source within the operating
system?
Depending on the software you are using, you may need to specify the UA-25 as the
audio data input source for your computer. For details on this setting, refer to"Driver
settings" (p. 26), "Input/output device settings" (p. 34), "OMS settings" (p. 38),
"FreeMIDI settings" (p. 41).
Data that contains the SCMS flag cannot be recorded digitally.
The UA-25 supports SCMS, so that if SCMS-flagged data (such as data from an MD that
was digitally copied from a commercial music CD) is input to the digital connector, the
UA-25 will not be able to record this on the computer.
The sound will be output from the line output jacks and the headphone jack.
You will become unable to record if you switch the sampling frequency (e.g.,
switch between digital broadcast mode A and mode B) of your digital device
while it is still connected to the digital input jack.
If you switch the sampling frequency, reconnect the digital cable.
Can't play/record 24-bit audio data
Does your software support 24-bit audio data?
You will need to use software that supports 24-bit audio data.
Is your software set to record/play 24-bit audio data?
Set your software to 24-bit.
