[alsa-lib]$ aplay -Diec958 file24bits.wav aplay: set_params:1059: Sample format non available Available formats:
- S16_LE
- S32_LE
Is there an built-in assumption that the iec958 device can only take as input what the slave hardware device supports?
Use 'plug:iec958' device if you want to do the format conversion (from 24-bit to 32-bit format).
That seems to work, but what I was asking is if there's a direct path without conversion? With plug:iec958 there's a conversion to 32-bits and then you drop the lsb. Also PulseAudio seems to rely on iec958 and when it doesn't work it tries with plug:iec958. What's the recommended way of using this device? Should we always open plug:iec958? Thanks -Pierre
