USB 2.0 5.1 sound card

The STARTECH ICUSBAUDIO2D is an external USB 2.0 audio adapter that adds 5.1 channel output and a digital SPDIF port to a computer. It uses the VIA VT1630A chipset and provides 96KHz sample rate with 91dB signal-to-noise ratio. The device is aimed at users who need surround sound or optical output on systems lacking built-in audio connections.

USB 2.0 bandwidth and OS limits

The USB 2.0 interface caps throughput at the legacy high-speed rate which restricts maximum channel count and sample depth compared to modern USB audio standards. Driver support ends at Windows 10 and Mac OS X 10.8 so newer operating systems may not recognise the device without community workarounds. No hardware controls or on-board DSP are present so all processing falls to the host CPU.

5.1 channels and 96KHz headroom

The adapter comfortably handles stereo and 5.1 playback at 96KHz for movies music and gaming headsets using the 3.5mm analogue or Toslink digital outputs. It runs out of headroom for higher sample rates multi-channel uncompressed formats beyond 5.1 or professional recording workflows that demand lower latency and higher dynamic range than the 91dB SNR provides.

Questions sur cet article

Should I pick the 5.1-channel version or a stereo-only model for surround sound?

This model delivers 5.1 channels through its VIA VT1630A chipset, so you get full surround output from a single USB 2.0 connection.

What does the 96 kHz sample rate mean for my music and movies?

It supports playback up to 96 kHz, so high-resolution audio files play at their native rate without down-sampling.

Does the USB 2.0 interface limit the 91 dB signal-to-noise ratio in practice?

USB 2.0 provides enough bandwidth for the 96 kHz stream, so the 91 dB SNR is achievable in real use.
