Please, verify kernel 3.10.5: HDA and AC97 audio is ok now?

[NicCo]

DESCRIPTION:
It has been reported by dago68 and verified also by me, that there are very ugly audio issues with the HDA audio.
Perhaps the same issues may be present also with AC97: this has not been tested by the lacking of such hardware.

Every time that some audio contents must be played:
it starts with some noises lasting a few secs, or a audio bump, or even worse one missing channel (left or right)...

On 11 June, we changed some important kernel keys since these kernels:
3.9.1-1, 3.9.1-69 then into kernel 3.8.13-2, kernel 3.8.13-69.2, and so on...

from
CONFIG_SND_HDA_POWER_SAVE_DEFAULT=0
CONFIG_SND_AC97_POWER_SAVE_DEFAULT=0
to
CONFIG_SND_HDA_POWER_SAVE_DEFAULT=10
CONFIG_SND_AC97_POWER_SAVE_DEFAULT=10

thus adding Power Saving Audio enabling audio idle when after 10 secs of inactivity

That was the result of of a part of an accepted proposal (by POK)

Every time that some audio contents must be played:
it starts with some noises lasting a few secs, or a audio bump, or even worse one missing channel (left or right)...

I suppose that the audio power save can be the culprit of this bad behaviour, so from next kernel version, to verify this,
I have reverted the configuration to NO Audio Power Save for HDA and AC978 audio with the incoming kernel 3.10.5...

Testing request: ONLY if you have had these above described audio issues:
all kernels since 3.9.1-1, 3.9.1-69, 3.8.13-2, kernel 3.8.13-69.2, up to 3.10.4, now are suffering the audio issues

When you'll install new Kernel 3.10.5, please, verify if audio is finally OK,
also when you start some audio streams after some time of unactivity!

(This comparison must be done with all other kernels that we made since 11 June upto kernel 3.10.4)



Thanks
