Hello,
today when I boot the problem already appears (emu10k1 appears already greyed out in systemsettings), but everything is ok with lsmod, looks more a KDE problem:
snd_emu10k1 172032 1
snd_util_mem 16384 1 snd_emu10k1
snd_ac97_codec 139264 1 snd_emu10k1
snd_hwdep 16384 2 snd_emu10k1,snd_hda_codec
snd_pcm 110592 6 snd_hda_intel,snd_emu10k1,snd_hda_codec,snd_hda_core,snd_ac97_codec,snd_hda_codec_hdmi
snd_rawmidi 32768 2 snd_emu10k1,snd_mpu401_uart
snd_timer 36864 2 snd_emu10k1,snd_pcm
snd_seq_device 16384 2 snd_emu10k1,snd_rawmidi
snd 90112 15 snd_hda_intel,snd_emu10k1,snd_hwdep,snd_hda_codec,snd_ac97_codec,snd_timer,snd_mpu401_uart,snd_rawmidi,snd_hda_codec_hdmi,snd_seq_device,snd_pcm
emu10k1_gp 16384 0
gameport 16384 3 ns558,emu10k1_gp
Will try with du and see what happens.
