Hello everybody I hope I can get some help here. My system is: ------------- Dell XPS One 2710, Ubuntu 12.04, Kernel 3.2.0.31 or 3.2.0.32 or 3.6.2 The Problem is: --------------- Sound works out of the box, until machine is suspended to RAM (STR). After resume there is no sound at all. Interestingly, a suspend to Disk (STD) and resume restores sound functionality! aplay -l: Karte 0: PCH [HDA Intel PCH], Gerät 0: ALC275 Analog [ALC275 Analog] Sub-Geräte: 1/1 Sub-Gerät #0: subdevice #0 Karte 0: PCH [HDA Intel PCH], Gerät 3: HDMI 0 [HDMI 0] Sub-Geräte: 1/1 Sub-Gerät #0: subdevice #0 lsmod|grep snd: snd_hda_codec_hdmi 32506 1 snd_hda_codec_realtek 79668 1 snd_hda_intel 34147 3 snd_hda_codec 135374 3 snd_hda_codec_hdmi,snd_hda_codec_realtek,snd_hda_intel snd_hwdep 13668 1 snd_hda_codec snd_pcm 97661 3 snd_hda_codec_hdmi,snd_hda_intel,snd_hda_codec snd_timer 29989 1 snd_pcm snd 79391 13 snd_hda_codec_hdmi,snd_hda_codec_realtek,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_pcm,snd_timer soundcore 15091 1 snd snd_page_alloc 18572 2 snd_hda_intel,snd_pcm I tried to reload alsa modules to restore sound, but it is not possible to unload or reload snd modules: # sudo /sbin/alsa force-unload Unloading ALSA sound driver modules: snd-hda-codec-hdmi snd-hda-codec-realtek snd-hda-intel snd-hda-codec snd-hwdep snd-pcm snd-seq-midi snd-rawmidi snd-seq-midi-event snd-seq snd-timer snd-seq-device snd-page-alloc (failed: modules still loaded: snd-hda-codec-hdmi snd-hda-codec-realtek snd-hda-intel snd-hda-codec snd-hwdep snd-pcm snd-timer snd-page-alloc). All information in the net that I found is unfortunately either depreciated (using acpi_suspend) or refers to other chips that have options (e.g. modprobe snd_hda_intel option=acer). It seems, there is no documentation about options of the ALC275 chip available. Anybody has a solution or a hint for me how to fix this?
