[Jack-Devel] Does alsa_in reading from SPDIF input inject pops and clicks?

[crocket]

I am considering

* Creative Sound Blaster X-Fi HD USB for headphone jack and SPDIF In.
* StarTech.com 7.1 USB Sound Card with
https://www.viatech.com/en/silicon/legacy/audio/vt1630a/ chipset for SPDIF
Out, SPDIF In, and headphone jack.
* Realtek ALC887 onboard soundcard for SPDIF out and potentially headphone
jack.

Obviously, X-Fi HD has far higher signal to noise ratio for DAC.
But, for SPDIF In,  StarTech.com 7.1 USB soundcard might be cheap and good
enough. VT1630A might also have a better implementation of SPDIF out that
emits clock signals in the absence of audio signals.
But, everything here is a speculation since I haven't tested any.
