Whenever I cold boot my system I get sound blasted by static. When I reboot the static disappears and the sound works properly.
PC Info:
- Motherboard - MSI h77ma-g43
- Sound Card - Creative Sound Blaster Audigy FX 5.1 Sound Card SB1570
- Graphics Card - GeForce GTX 460
- Operating System - Ubuntu 14.04
I've disabled the onboard audio in BIOS
If I lspci -vv
I noticed there is a second Audio device listed which I believe is the graphics card's HDMI audio.
$ lspci -vv

Both are listed as using the same Kernel driver snd_hda_intel
. I'm not sure if that could be causing an issue.
Since the sound works flawlessly after reboot I've been wondering if the issue could be the OS loading too fast for the sound card to properly initialize?
Let me know if you need any other info.
