dmesg with Linux 4.5
There is no "error DSP boot timeout" with Linux 4.5, however audio still not working (no sound adapters detected). "Baytrail Audio Port: ASoC: no backend DAIs enabled for Baytrail Audio Port" error message get repeated many more times in comparison with Linux 4.4.
Please look into attached dmesg.

dmesg with 4.5 and acpi_ipc_irq_index = 0
With acpi_ipc_irq_index = 0 (/sound/soc/intel/atom/sst/sst_acpi.c) firmware downlading seems successful:

Hundreds of "no backend DAIs enabled for Baytrail..." errors in dmesg with Asus T100-CHI starting with kernel 4.5.0-rc4 through 4.6-rc1-next. CHI Uses rt5640 also. There is a dmesg posted for bug#114561 with other details. + Vinod whose team own the driver. Thanks for your email I am attending ELC-NA, pls expect delayed response Regards -- ~Vinod This issue is being handled in #117141. Can you attach the output of dmidecode, so that the DMI system identification can be added to the quirk-table in fix patch-set attached to that bug? I am hoping for progress on this as I think this might solve the problem with broken sound on the Toshiba Click Mini as well. The following error about the missing backend DAI is due to the missing Alsamixer settings: [ 23.165318] Baytrail Audio Port: ASoC: no backend DAIs enabled for Baytrail Audio Port In this driver we use DPCM, which means that you have to route Front End to a BackEnd and then only you can open a device. Without linking to BE it will fail. Would you please post the output of the command "aplay -l" to check if a sound card is getting created or not. If it is getting created, the output of "aplay -l" should look something like: card 0: baytrailcraudio [baytrailcraudio], device 0: Baytrail Audio (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 If sound card is getting created, you can proceed with executing the following amixer commands: For Playback: #DSP routing amixer -c0 sset 'codec_out0 mix 0 pcm0_in' on amixer -c0 sset 'media0_out mix 0 media1_in' on amixer -c0 sset 'media1_in Gain 0' 80% amixer -c0 sset 'media1_in Gain 0 Ramp Delay' 50 amixer -c0 sset 'media1_in Gain 0' off amixer -c0 sset 'pcm0_in Gain 0' 80% amixer -c0 sset 'pcm0_in Gain 0 Ramp Delay' 50 amixer -c0 sset 'pcm0_in Gain 0' off amixer -c0 sset 'codec_out0 Gain 0' 80% amixer -c0 sset 'codec_out0 Gain 0 Ramp Delay' 50 amixer -c0 sset 'codec_out0 Gain 0' off #Codec routing amixer -c0 sset "DAC MIXL INF1" on amixer -c0 sset "DAC MIXR INF1" on amixer -c0 sset "Stereo DAC MIXL DAC L1" on amixer -c0 sset "Stereo DAC MIXR DAC R1" on amixer -c0 sset "SPK MIXL DAC L1" on amixer -c0 sset "SPK MIXR DAC R1" on amixer -c0 sset "SPOL MIX SPKVOL L" on amixer -c0 sset "SPOR MIX SPKVOL R" on amixer -c0 sset "SPOL MIX DAC L1" on amixer -c0 sset "SPOR MIX DAC R1" on amixer -c0 sset "Speaker L" on amixer -c0 sset "Speaker R" on amixer -c0 sset "Headphone" off amixer -c0 sset "Ext Spk" on Hope this helps!
