While browsing idly the Internet, I found a topic on a computer forum when a person was claiming to have failed to achieve bit-perfect¹ audio on Linux: http://www.bleepingcomputer.com/forums/t/617127/sorry-guys-no-more-linux-for-me/ He says he has quit using Linux for this very reason.
Is it really impossible to achieve bit-perfect audio on Linux for any fundamental reason? If not, how to do this?
¹ Bit-perfect is a strict term; it means that the audio output is identical to the input – for example, if audio output is redirected to an USB drive, then the resulting file will be identical to the original file. Audio that has been resampled, or that has passed through a mixer, is not bit-perfect.
