[xiulipan]

After remove wait in dai trigger stop/puase we need also to
restore pointer for start just like release.
Now same behavior for stop/start and pause/release.

@lgirdwood
There still be another noise issue with firmware xrun.
From log seems to be that the irq_task could not enter the irq in time.Then cause some pipeline task timeout.

What messages in the trace would indicate this xrun? I am not seeing any xru/Xru in rmbox but I am hearing a lot of noise and usually just closing and reopening the stream fixes or brings the bug back.

[lgirdwood]

@cujomalainey this is usually propagated up the stack, aplay would print this out and make it really obvious. The firmware can also log these too, rmbox should show them.

[cujomalainey]

Hmm, I'm not seeing anything anywhere, it must not be underruns I'm seeing. But I am getting a lot of noise. I'll file another bug to track it.
