3.19.5.1 Conﬁguration 2ioxs

This conﬁguration runs in high-speed Audio Class 2.0 mode, has the mixer disabled,

supports 2 channels in, 2 channels out, supports sample rates up to 192kHz and

S/PDIF transmit.

3.19.5.2 Conﬁguration 2iomx

This conﬁguration disables S/PDIF and enables MIDI.

This conﬁguration can be achieved by in the Makeﬁle by deﬁning SPDIF as zero:

- D SPDIF =0

and MIDI as 1:

- D MIDI =1

3.19.5.3 Conﬁguration 2ixxx

This conﬁguration is input only (

NUM_USB_CHAN_OUT

set to zero). I.e. a microphone

application or similar.

3.19.5.4 Conﬁguration 1ioxs

This conﬁguration is similar to the ﬁrst conﬁguration apart from it runs in Audio

1.0 over full-speed USB.

This is achieved in the Makeﬁle by:

- DAUDIO_CLASS =1

3.19.5.5 Conﬁguration 1xoxs

This conﬁguration is similar to the conﬁguration above in that it runs in Audio 1.0

over full-speed USB. However, the it is output only (i.e. the input path is disabled

with -DNUM_USB_CHAN_IN=0
