Subject: [PATCH 03/14] USB-Audio: Add second S/PDIF device on Phiree U2
|
||
|
|
|
||
|
|
Phiree U2 has an unusual configuration. It only has S/PDIF output, but
|
||
|
|
there are still two devices presented:
|
||
|
|
- device 0: PCM audio, subject to volume control
|
||
|
|
- device 1: non-PCM data (passthrough), not subject to volume control
|
||
|
|
|
||
|
|
It looks like the AES bits are set according to the selected device,
|
||
|
|
since outputting PCM data via device 1 will not work (silence).
|
||
|
|
|
||
|
|
Currently only the device 0 is shown via the "iec958" alias, and the
|
||
|
|
second device is not accessible via hinted aliases.
|
||
|
|
|
||
|
|
Simply provide access to both of these devices via the "iec958" alias.
