21.3 Supported Sample Rates

RME's Mac OS X driver supports all sampling frequencies provided by the hardware. Besides

192 kHz and 96 kHz this also includes 32 kHz and 64 kHz.

But not every software will support all the hardware's sample rates. For example Spark does not

display 32 kHz and 64 kHz. The hardware's capabilities can easily be verified in the Audio MIDI

Setup. Select Audio devices under Properties of: and choose the Hammerfall DSP. A click on

Format will list the supported sample frequencies.

If the unit is in clock mode Master, selecting a sample rate will immediately set the device to

this frequency, which can be verified in the HDSP's settings dialog (System Clock). Format thus

allows you to activate any sampling frequency quickly and easily.

21.4 Repairing Disk Permissions

Repairing permission can solve problems with the installation process - plus many others. To do

this, launch Disk Utility located in Utilities. Select your system drive in the drive/volume list to

the left. The First Aid tab to the right now allows you to check and repair disk permissions.

21.5 PCI card and PCI slot compatibility

Unfortunately not every RME card will work in every PCI slot of an Apple computer. To our

knowledge, the current Hammerfall DSP systems can be used in any PCI slot of all G4 and G5

models. In case additional PCI cards of any manufacturer are used, it might happen that the

RME card is no longer found by the system. Swapping cards between slots can be helpful in

this case.

21.6 Various Information

The driver requires 10.2.8 or higher. Older versions of OS X are not and will not be supported.

Via >System Preferences/ Audio-MIDI Setup< the hardware can be configured for the system

wide usage. Programs that don't support card or channel selection will use the device selected

as Standard-Input and Standard-Output. (Soundstudio, Mplayer, Amplitube etc.).

In the lower part of the window, the audio hardware's capabilities are shown and can be

changed in some cases. On the record side no changes are possible. Programs that don't sup-

port channel selection will always use channels 1/2, the first stereo pair. To access other inputs

use the following workaround with TotalMix: route the desired input signal to output channels

1/2. Hold the Ctrl key down and click on the labels AN1 and AN2 in the third row. Their labels

turn red, the internal loop mode is active. Result: the desired input signal is now available at

input channel 1/2, without further delay/latency.

Since OS X 10.3 playback can be configured freely and to any of the available playback chan-

nels. This is done via Speaker Setup. Even multichannel playback (Surround, DVD Player) can

be set up easily.
