I recently switched to a new motherboard: Asus Z97-Deluxe
This motherboard has a ALC1150 audio chip, which uses the snd_hda_intel driver.
CPU: Intel i5-4670K
Kernel: 3.14.4-1-ARCH #1
alsa-info: https://drive.google.com/file/d/0Bymxsci1WxB1VF9vVHVMSFpjSm8/edit
Audio is playing bad: 'radio noise', skipping, repeating. It is unusable.
Before I used Pulseaudio, but to diagnose this problem I have removed it.
Now with Alsa left, it plays a little bit better, but the problem is still there.
The only moment when the audio works great is when the CPU is busy, such as compiling a Linux kernel.
Sometimes moving the mouse gives a slight improvement due to less skipping; although the 'scratching' stays.
The following module options have been tried but without success, with each option I have rebooted the system.
* options snd-hda-intel enable_msi=1

* options snd-hda-intel enable_msi=1
* options snd-hda-intel enable_msi=0
* options snd-hda-intel bdl_pos_adj=-1
* options snd-hda-intel bdl_pos_adj=1,48
* options snd-hda-intel bdl_pos_adj=-1,64
* options snd-hda-intel power_save=0
In Arch I do get a warning in dmesg, which I can't resolve by using the above options.
* hda-intel: IRQ timing workaround is activated for card #0. Suggest a bigger bdl_pos_adj.
The addition of the kernel parameter (suggested by another user) did not help either.
* GRUB_CMDLINE_LINUX_DEFAULT="processor.max_cstate=2"
When I run directly from the Linux Mint 16 x64 LiveDVD, it has the same issue.
My gut feeling tells me the cause might be the BIOS, the driver, power management or CPU scheduler.
Since I have been searching for about two days straight and trying most of the offered obvious solutions, I am now searching for active help.
Any suggestions how to approach this audio issue?
