Hi, Takashi I'm a nvidia engineer. We plan to develop the new hdmi audio driver for the new chipset. It support the latest HD Audio Specification. I download the latest kernel source, it has patch_intelhdmi.c. And this file have many defines and routines for HDMI operations. If I develop hdmi driver, it also need to define the same functions in patch_nvhdmi.c, it seems not very well. Do you have plan to change these codes to common code? I think these codes are common for HDMI audio.
BTW I have a another question. Because the standard ALSA channel mapping is different with the Windows setting. So we could use channel-slot assignment (verb 0x734) to fix. How can I know the audio is using ALSA setting or Windows setting? Does there have any mechanism to support this operation?
Thanks Wei.
