Does anyone use these interfaces on Linux? If so, how do the inputs map (e. g. with ALSA/PulseAudio)?
E. g. the Scarlett 6i6 has the following connections.
- 2x symmetric XLR inputs (one for each channel)
- 2x symmetric phone connector inputs (one for each channel)
- 1x coaxial SPDIF input (stereo signal over a single wire)
- 4x symmetric phone connector output
- 1x coaxial SPDIF output (stereo signal over a single wire)
Each input has its own ADC and each output has its own DAC, so there's nothing that goes "through" to another channel.
Now my question is: How does this map onto audio channels under Linux?
Output-wise: Is it recognized as a single 6-channel card, so e. g. phone connector 1 is "front left", phone connector 2 is "front right", phone connector 3 is "rear left", phone connector 4 is "rear right", SPDIF channels are front and LFE or similar, "awkward" situation? Or is it recognized as three separate stereo audio cards? Or is even each output a single mono audio card? Or how?
Input-wise: Do the 2x symmetric XLR inputs form a "stereo pair", so that when I plug a microphone into one, then record, I only get signal on, say, left channel, and the right one is silent? Or do they act as two separate mono inputs? What with the other inputs?
Would be great if someone had this interface running under Linux and could give me some insights. I plan plugging a condenser mic into the interface via XLR and would be interested if the two XLRs act as a "stereo input" and when I record, I get signal on one channel but not on the other or how this would turn out.
