Comment 839 for bug 1958019

I noticed that patch is present in the kernel I am running...

"dmesg | grep 2781" yields nothing.

"lsmod" indicates snd_hda_scodec_tas2781_i2c is loaded.

I'm quite green with the audio subsystem in linux, so pretty overwhelmed and suprised how complicated it is :) I'm not 100% sure, but it sounds like there is firmware and associated tuning values present in the EFI system that are also required.

One other thing I noticed, running "i2cdetect -r 3" doesn't report any probed addresses. -r 1 has one at 0x14, -r 2 has at 0x2c, less that I think expected based on other similar posts.
