[ALSA] ice1724 - Add support of Chaintech AV-710
Documentation,ICE1724 driver Add the support of Chaintech AV-710 to ice1724 driver. The patch includes the WM-codec initialization fix by Jaanus Kivistik <jaanus@no.spam.ee>. Since both AV-710 and AMP Audio2000 have the same SSID, initialize WM codecs as default for both devices. In case it breaks Audio2000, you can pass 'model=amp2000' option to avoid WM codec initialization. Signed-off-by: Takashi Iwai <tiwai@suse.de>
