This patch is NOT OK for ABE standpoint. Multimedia port is working only at 48 or 44.1 kHz. If you try to set it at different rate some Sample rate converter will be missing on the path.
On this kernel release ABE internal is running at 48 or 44.1 kHz. When making you patch to enable 32 kHz you are doing the assumption that ABE will do the sample rate conversion between 32 to 48. This block is not part of the Firmware.
So here you have no choice for 32 kHz you need to have SW SRC at ALSA or PulseAudio level.
Also for Volume setting you should always be around 120 (0 dB). Here setting the volume to 149 means +29 dB. So your input signal should be very low.
