I am not sure. I think power_save=0 means that there is no timeout and snd-hda-intel never sleeps. My previous kernel (vanilla 2.6.32) did not have CONFIG_SND_HDA_POWER_SAVE set, so the power_save was not even an option, and it all worked fine. There are also bug reports of some high pitch noise related to the power_save=10 setting, both in Fedora and in Ubuntu. -- Nick Zhuravlev www.auriga.com On Sun, Feb 14, 2010 at 02:26:08PM -0400, Bjorn Wielens <Uniacke1@xxxxxxxx> wrote: > so it looks like if the hda driver is in a sleep state, the agrsm driver > has a fit. > > > I just verified that my SuSE distro does not set the power save in > modprobe, hence it worked fine out of the box for me. > > That said, it must be possible to modify the driver code to "wake" the > sound card properly- I know for a fact that it has function prototypes > for powerup/powerdown functions. > > Bjorn. > > > On 02/14/2010 01:57 PM, Nikolay Zhuravlev wrote: > > Valera, > > > > Glad it worked for you.
