For some reason I don't have any sound after suspend/standby on Ubuntu 14.04.1.

It happens on a XMG C504, and the online solutions do NOT work.

According to alsamixer the 0 is a Intel Haswell HMDI and the 1 is a Realtek ALC282

cat /proc/asound/cards
 0 [HDMI           ]: HDA-Intel - HDA Intel HDMI
                      HDA Intel HDMI at 0xf7414000 irq 53
 1 [PCH            ]: HDA-Intel - HDA Intel PCH
                      HDA Intel PCH at 0xf7410000 irq 52

lspci | grep -i audio
00:03.0 Audio device: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor HD Audio Controller (rev 06)
00:1b.0 Audio device: Intel Corporation 8 Series/C220 Series Chipset High Definition Audio Controller (rev 05) 

lsmod | grep -q snd_hda_intel
lsmod | grep -q snd_foo

return no result

This does not work

sudo alsa force-reload

Or this

pulseaudio --kill
pulseaudio --start

--- EDIT ---

The most funny thing is, if I play something, putt the volume wide open and then mute it it plays for a fraction of a second, this only happens when muting not when unmuting.

--- EDIT ---

Another strange thing, sound over HMDI does work after suspend/standby... switching back to the speakers doesn't... even after repeatedly switching between HDMI and speakers...

--- EDIT ---

To help as much people as possible, the following systems seem to be affected by this bug, all based on the Realtek ALC282;

  • XMG C504 (Based on the Gigabyte P35 series)
  • Gigabyte P35w v2
  • Gigabyte P35x v4

  • Finally! Someone with the same issue! I did find out that Windows does have the same problem but not all the time.

Same issue on Kubuntu 15.04, Realtek ALC282.

Here is a workaround:

  1. Suspend/resume: no sound threw the speaker
  2. Mute the audio with the keyboard (no GUI) : Fn + Mute
  3. Increase the audio with the keyboard (no GUI) : Fn + VolumeUp
  4. Sound is back!
