ALSA: usb-audio: Add mixer workaround for TRX40 and co
Some recent boards (supposedly with a new AMD platform) contain the USB audio class 2 device that is often tied with HD-audio. The device exposes an Input Gain Pad control (id=19, control=12) but this node doesn't behave correctly, returning an error for each inquiry of GET_MIN and GET_MAX that should have been mandatory. As a workaround, simply ignore this node by adding a usbmix_name_map table entry. The currently known devices are: * 0414:a002 - Gigabyte TRX40 Aorus Pro WiFi * 0b05:1916 - ASUS ROG Zenith II * 0b05:1917 - ASUS ROG Strix * 0db0:0d64 - MSI TRX40 Creator * 0db0:543d - MSI TRX40 BugLink: https://bugzilla.kernel.org/show_bug.cgi?id=206543 Cc: <stable@vger.kernel.org> Link: https://lore.kernel.org/r/20200408140449.22319-1-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
