ALSA: usbaudio: Fix wrong bitrate for Creative Creative VF0470 Live Cam
This patch works around misbehaviour of Creative Creative VF0470 Live Cam which reports 16 kHz sample rate for audio capture while actually producing 8 kHz stream. Signed-off-by: Arseniy Lartsev <arseniy@fizlesh.ru> Signed-off-by: Takashi Iwai <tiwai@suse.de>
