The IT66121 is an HDMI transmitter and does not support audio capture. However, the driver registers hdmi-codec without setting no_i2s_capture, causing the codec to advertise a non-functional capture stream. Userspace audio servers such as PulseAudio then attempt to open this capture device, resulting in errors.
Set no_i2s_capture and no_spdif_capture in hdmi_codec_pdata so that the hdmi-codec driver only registers playback, matching the actual hardware capability.
