Hi

I have an Ivy Bridge with an Intel i7-3770S (ASUS P8H77-M LE). My sound output goes via SPDIF to an H/K AVR 65. Before upgrading to the Ivy Bridge everything worked fine, but after upgrading I am starting to get a very irritating hum noise. The strange thing is that it only happens when i playback content in 48 kHz. If i try to play music content, which usually is in 44.1 kHz, the noise goes away, but switching back to content with 48 kHz, the noise comes back. The noise is similar to the sound you get when you have a grounding issue, but it's defiantly not a ground problem, as I've had those before, and know how to fix it..

After playing back any 48 kHz content the noise is still there, as I assume the 48 kHz "channel" is this open or something, but if i mute the SPDIF output channel in alsamixer or playback some 44.1 kHz content the noise goes completely away.

I am currently running the gentoo-sources 3.3.8, and to verify if this was a Gentoo issue I tried testing with a MythBuntu 12.04 LiveCD, and the issue is not present. But I did note a somewhat similar behavior thought. As mplayer was finished playing back the content, I could hear the hum noise for half a second, before it automatically got muted down. MythBuntu does not actually mute down the SPDIF channel, but it sounded just as if I something had done it like that.

I did try to check the asound configuration of the MythBuntu LiveCD, but I couldn't find any interesting stuff.

Does any know what kind of problem this is? And how I can get the same behavior of Alsa on my Gentoo box. Is there special kernel switch, alsa module or asound configuration that I must tweak?

Espen

Just this would tend to make me suspect some trouble in resampling.
Provide all information about your sound configuration (including asound.conf, ~.asoundrc, sound server...)

I have nothing in my asound.conf or ~.asoundrc. For playback I usually use mplayer with ao=alsa:device=spdif on commandline or in .mplayer/config. To get all info about alsa i used their alsa-info.sh script, which gave me this:

My custom kernel config is below that again.
