Hello! I have a Lenovo ThinkPad X220 laptop with a conexant codec and recently (after kernel 3.5.2) it is active all the time after KDE login, as powertop says. This couldn't be fixed by logging of from KDE or playing some music in mplayer from console. The only kernel I tried in 3.5.x is 3.5.2, so I can't say is this bug reproducible in 3.5.0 or 3.5.1, but everything is fine with 3.4.9. This never happens if you don't start KDE after reboot, you can listen to some music in mplayer in console and everything seems to be fine. lsof and fuser /dev/snd/* shows nothing. Thank you! $ cat /etc/modprobe.d/options.conf options snd-hda-intel power_save=1 power_save_controller=1 $ lspci -nn | grep Audio 00:1b.0 Audio device [0403]: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller [8086:1c20] (rev 04) $ lsmod | grep snd snd_hda_codec_hdmi 23704 1 snd_hda_codec_conexant 47158 1 snd_hda_intel 25700 2 snd_hda_codec 97400 3 snd_hda_codec_hdmi,snd_hda_codec_conexant,snd_hda_intel snd_hwdep 6300 1 snd_hda_codec snd_pcm 74926 3 snd_hda_codec_hdmi,snd_hda_codec,snd_hda_intel snd_page_alloc 7185 2 snd_pcm,snd_hda_intel snd_timer 18966 1 snd_pcm snd 60021 12 snd_hwdep,snd_timer,snd_hda_codec_hdmi,snd_hda_codec_conexant,snd_pcm,snd_hda_codec,snd_hda_intel,thinkpad_acpi soundcore 5442 1 snd ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
