What if the sound device calibration fails?
There are a number of possible causes for a sound device calibration to fail: 1. The problem could be as simple as an incorrect connection between the selected input and output. Also make sure to use a (short) shielded cable, to minimize interference. 2. Not all sound devices support all sample frequencies. Many current sound devices have the hardware laid out for a single sample frequency (often 48000 Hz for AC’97 codecs), and use sample rate conversion algorithms for other sample frequencies. Sometimes these algorithms produce results that are unusable for Dirac. 3. Some sound device manufacturers make near perfect hardware, but manage to write drivers that make the sound device almost useless. Switching drivers may help in this case. 4. The load on your processor may be too high. The calibration procedure uses a lot of processing power. Running compute intensive programs in the background may prevent Dirac from completing the calibration procedure. In particular, we have seen proble
