Professional USB Audio Controller for 5.1 Surround

The weastlinks USB Sound Card uses a C-Media CM6206 chipset to deliver 5.1 channel analogue output and stereo S/PDIF digital I/O. It targets laptop and desktop users who need discrete multi-channel audio without opening the case. The device draws power and data from a single USB connection. Buyers who require 7.1 channel decoding or hardware DSP effects will not find those features here.

Sampling Rates and Digital Interface Limits

Analogue recording and playback are fixed at 48 kHz while digital recording can lock to 32 kHz, 44.1 kHz or 48 kHz automatically. Digital playback is restricted to two-channel PCM over S/PDIF following AES/EBU and IEC 60958 consumer standards. Six-channel audio is only available through the analogue outputs. Users needing bitstream pass-through of encoded surround formats cannot use the optical link for that purpose.

Driver-Free Installation and Common Pitfalls

The adapter operates as a standard USB audio class device so no proprietary driver is required on modern operating systems. Simply plug the unit into a free USB port and select it as the default playback or recording device. Problems usually arise when the host USB controller cannot supply clean power or when the OS defaults back to the internal audio device after sleep.

Questions about this item

Does the 5.1-channel version support full surround output or only stereo over the optical link?

In digital playback mode only the left and right PCM channels pass through the optical output. The six analogue channels are available only when using the analogue outputs.

What does the 48KHz sample-rate figure mean for everyday recording and playback?

The chipset fixes analogue recording and playback at 48KHz. Digital recording can also lock to 32KHz or 44.1KHz when the source provides those rates.

Which USB standard does the CM6206 use and does it limit the channel count?

The controller connects through a standard USB audio interface. Channel count is limited by the chipset itself: six analogue channels, but only stereo PCM over the digital optical path.
