Problems with sound on Realtek ALC272

Hi, guys!

I have been trying to get my Realtek ALC272 to work on FreeBSD 10, it looks like the system can detect it, but when I try to play something I see the error.

Code: 
pcm0: chn_write(): pcm0:virtual:dsp0.vp0: play interrupt timeout, channel dead
Edit:
Additionally I have noted this when setting hw.snd.verbose to 4 :

Code: 
pcm0: chn_sync(): [stalled] timeout=10 count=137 hcount=138 resid=130736 minflush=0

Thanks in advance.

Code: 
cat /boot/loader.conf
sound_load="YES"
snd_driver_load="YES"
snd_hda_load="YES"

Code: 
cat /dev/sndstat
pcm0: <Realtek ALC272 (Analog 2.0+HP/2.0)> (play/rec)

You do not need any of that in /boot/loader.conf.

According to this, the Intel Cougar Point HDMI is the default play device. Does it help if you execute sysctl hw.snd.default_unit=0 before you try to play something?
 
I've checked that, I set pcm0 as default

Code: 
cat /dev/sndstat
Installed devices:
pcm0: <Realtek ALC272 (Analog 2.0+HP/2.0)> (play/rec) default
pcm1: <Intel Cougar Point (HDMI/DP 8ch)> (play)
pcm2: <USB audio> (rec)

with the same problem:

Code: 
pcm0: chn_write(): pcm0:virtual:dsp0.vp0: play interrupt timeout, channel dead
pcm0: chn_write(): pcm0:virtual:dsp0.vp0: play interrupt timeout, channel dead

:\ I don't have any idea about what could be.
