Yes this is a problem, which FW are you using
Have you tried the recent kernels, Pierre did a bunch of update and got many things working.
As for timeout, that simply means we have send a message to DSP which failed to get a response. Perhpas the message had some bad element of FW had a bug/crashed...
The firmware timeout is due to a change in the BIOS for BYT-CR devices that impacts the IPC interrupt number, I have a set of patches that fix this on Asus T100TAF but I still can't get any sound out.
Hi!
So, it seems I got dsp interrupts after the timeout errors. I added dev_dbg(drv->dev, "Interrupt received\n"); to the intel_sst_interrupt_mrfld() function
