[PATCH v6 4/9] ALSA: virtio: build PCM devices and substream hardware descriptors

Like the HDA specification, the virtio sound device specification links PCM substreams, jacks and PCM channel maps into functional groups. For each discovered group, a PCM device is created, the number of which coincides with the group number. Introduce the module parameters for setting the hardwa
