Default Only Stereo Sound over HDMI after suspend 2 ram (updated)

Hi,

I use Debian unstable with KDE 4.7.4-1. To suspend the PC I use the command
Code:
 echo -n 'mem' > /sys/power/state
, which works perfectly for me. But I can only get Stereo sound over HDMI.
I have to stop KDE and reload the snd-hda-intel module in order to get 5.1 sound again.

I hope this can be fixed somehow.

Thanks,
neosmatrix

EDIT:

I found a small programm named hda-analyzer:

Code:
#### codec-1

Codec: 0x10de000a
Address: 1
AFG Function Id: 0x1 (unsol 0)
Vendor Id: 0x10de000a

#### Node [0x04] AUD_OUT

  Converter: stream=6, channel=0

  PCM:

  Pincap 0x09000094: OUT Detect HBR HDMI DP
  Pin Default 0x18560010: [Jack] Digital Out at Int HDMI
    Conn = Digital, Color = Unknown
    DefAssociation = 0x1, Sequence = 0x0
  Unsolicited: tag=0x01, enabled=1
  Connection: 1
     0x04
maybee this helps a bit.

EDIT2:

After another suspend and wakeup sound over HDMI is stereo again and the only difference i can see ind hda analyzer is here:
Code:
Node 0x04 [Audio Output] wcaps 0x72b1: 8-Channels Digital Stripe CP
  Converter: stream=0, channel=0
  Digital:
  Digital category: 0x0
  PCM:
    rates [0x7f0]: 32000 44100 48000 88200 96000 176400 192000
    bits [0xe]: 16 20 24
    formats [0x5]: PCM AC3
  Unsolicited: tag=0x00, enabled=0
Digital is off and the Converter values are different.

BTW. why are the only displayed formats PCM and AC3 ? I have a Sony STR-DG720 connected to a LG 37LF2510-ZB.
