Hello guys. I have been trying to get sound on my Asus T100TAF with rt5642. I have been following your various threads but i'm not succesfull with getting sound working. Hoppfully you can give me a hand
The changes i made to the kernel:

That wont work, I have verfied with T100, it is SSP2 based, so SSP0 will nto work here. I am trying to get this tested on latest driver and provide a working config. Will update shortly

even with .acpi_ipc_irq_index = 5 the output of the interupts while playing is: pinkflozd@bazdara-t100taf:~$ cat /proc/interrupts | grep sst 6: 0 0 0 0 IO-APIC 28-fasteoi intel_sst_driver
In both situations there is just huge heat coming from the speaker and a few clicks not related to playing sound
The T100TAF (Atom Z3535G & rt5642) seems to be using different interrupts order than the T100TA (AtomZ3775 & rt5640)
Interrupt (ResourceConsumer, Level, ActiveLow, Exclusive, ,, ) { 0x0000001D, } Interrupt (ResourceConsumer, Level, ActiveLow, Exclusive, ,, ) { 0x00000018, } Interrupt (ResourceConsumer, Level, ActiveLow, Exclusive, ,, ) { 0x00000019, } Interrupt (ResourceConsumer, Level, ActiveLow, Exclusive, ,, ) { 0x0000001A, } Interrupt (ResourceConsumer, Level, ActiveLow, Exclusive, ,, ) { 0x0000001B, } Interrupt (ResourceConsumer, Level, ActiveLow, Exclusive, ,, ) { 0x0000001C, }
I did try to sort them (based on Antonios suggestion) but got lots of errors when recompiling so i need to explore that a bit further

I did try the "old" driver for SSP0 that the guys with a T100TA are using but on the T100TAF doesn't work, so maybe the TAF is using something other than SSP2?
Please keep me CC'ed for any followups on this mater
Thanks
