If anyone has any objections, please let me know. ------------------ From: Cássio Gabriel commit 83fbbcb7935ec6d2c8ba3bc133e8a0ead2ab0b2d upstream. The VirtIO sound UAPI defines VIRTIO_SND_PCM_RATE_384000, and ALSA has SNDRV_PCM_RATE_384000. However, virtio-snd's rate conversion tables stop at 192 kHz. A device advertising only 384 kHz is rejected as having no supported PCM frame rates. A device advertising 384 kHz together with lower rates does not expose 384 kHz through the ALSA hardware constraints. The selected ALSA rate also needs a reverse mapping for SET_PARAMS. Add the missing 384 kHz entries to both conversion tables.
