Using the ASIO4ALL Advanced Settings
This section explains how to use the ASIO4ALL settings.
1. Open the Press the Audio settings (view page 46) and select 'ASIO
4ALL
v2' from the AUDIO INTERFACE list.
2. Click the [Control Panel] button on Audio settings to open the ASIO4ALL
driver settings (as shown below).
1. ASIO Buffer Size - As shown above, the ASIO4ALL window allows you to
adjust the ASIO Buffer Size (Buffer length) settings to fine-tune Buffer
underrun issues (audio clicks, pops or glitches). You can adjust the buffer
length for each selected device (in this case the Creative SB X-Fi is
selected, highlighted dark-blue). It is a good idea to set all devices you plan
to use to the same Buffer Size. Select each device by clicking on the name
so it becomes highlighted and then change the Buffer Size slider. The
Buffer Size is displayed in samples, to convert from samples to
milliseconds (ms) divide the Buffer length in samples by 44.1 (if your sound
card is using 44100 Hz) or 48 (if it is at 48000 Hz). In this case,the sound
card is set to 44100 Hz so the Buffer length of 448 samples = 10 ms
(approximately).
2. WDM Device List - The screenshot also shows 2 devices in the WDM
Device List (Creative SB X-Fi and Plantronics Headset). The devices that
appear in your list will probably be different and are those audio devices
that have sound card drivers correctly installed and registered with the
Windows operating system. If your sound is working correctly under
Windows, there should be at least one device listed (something with
Realtek or AC97 in the title are common for motherboard-based sound
cards). If nothing is showing in this list, re-install the soundcard drivers for
your PC, reboot and look here again.
