FireWire C hipsets
High definition audio flo wing over FireWire requires a consistent stream between the chipset i n the host computer and the chipset in the SCS1 device. Unfortunately, some FireWire chipsets have known issues when it comes to the reliability and synchronization required for streaming audio. It is suggested to use name brand PCI and PCMCIA cards such as Adaptec® when your PC does not have FireWire capabilities, as some no‐name or “OEM” FireWire cards will use chipsets of FireWire that have subpar performance and can affect stability or at worst the device will not work at all. Stanton recommends the Texas Instruments® FireWire chips for streaming audio. It is also suggested to stay away from Agere® chipsets as in testing issues have been identified with these chipsets. Most Apple com puters utilize Texas Instruments chipsets. However, it was reported that in late 2007 Apple had switched to Agere c hipsets for some production runs.
The easiest way to check if you have a Texas Instruments chipset is to run Device Manager and check the name of your host controller. (Figure A.23)
