The ASUS ROG Zenith II Extreme (TRX40) has two onboard USB audio codecs: - "Zenith II Main Audio" (0b05:1916, Realtek ALC1220-VB): PCM device 0 is the 8-channel analog output and the optical S/PDIF output is PCM device 1. Because the card is not in the iec958_device table, iec958: opened device 0, so the "Digital Stereo (IEC958)" output in PipeWire/PulseAudio sent audio to the analog jacks and the S/PDIF port was silent. - "Zenith II Front Headphone" (0b05:1915) has a single analog playback device and no digital output, but iec958: still opened it and PipeWire/PulseAudio listed a non-functional digital output. Tested on AlmaLinux 10.2 (alsa-lib 1.2.15.3, PipeWire 1.4.11): with this mapping, iec958:CARD=Audio opens hw:0,1 and audio plays over optical S/PDIF, and the front headphone codec shows up as analog stereo only.

Fixes #532
Adds the two onboard USB audio codecs of the ASUS ROG Zenith II Extreme (TRX40) to the
USB-Audio.pcm.iec958_devicetable:"Zenith II Main Audio" 1(0b05:1916, Realtek ALC1220-VB): S/PDIF is PCM device 1; device 0 is the 8-channel analog output. Without this,iec958:opened device 0 and the IEC958 output in PipeWire/PulseAudio played to the analog jacks."Zenith II Front Headphone" 999(0b05:1915): analog-only codec with no digital output, soiec958:should not open it.Tested on AlmaLinux 10.2 (alsa-lib 1.2.15.3, PipeWire 1.4.11):
iec958:CARD=Audioopenshw:0,1, audio plays over optical S/PDIF, and the front headphone codec shows up as analog stereo only.This change was created by Claude (Anthropic's Claude Opus 5.5, high effort) via Claude Code and tested as working on the affected hardware by Colin Byrne.
