I didn't have ALSA loopback so I could record streaming, so I upgraded ALSA following these instructions: http://alsa.opensrc.org/index.php/Jack_and_Loopback_device_as_Alsa-to-Jack_bridge#Compiling_snd-aloop_if_needed First thing: that page is WRONG. It instructs me to backup the kernel/sound directory: # p -a /lib/modules/`uname -r`/kernel/sound . "... In case anything went wrong and you wish to go back to your previous ALSA installation, no problem: sudo rm /lib/modules/`uname -r`/kernel/sound sudo cp -a ~/backup/sound /lib/modules/`uname -r`/kernel/ sudo alsa force-reload ... " But that is not enough. As soon as I ran 'sudo make install' I saw that another directory should have been backed up: if [ -L /usr/include/sound ]; then \ rm -f /usr/include/sound; \ I didn't make a backup of /usr/include/sound and now I am screwed. The backup /lib/modules/`uname -r`/kernel/sound directory doesn't work at all. My sound card is not even recognized when I boot with it. What about the new, upgraded ALSA modules? Well, they *look* OK, but I don't get any sound through the speakers or headphone jack. The only part I didn't follow verbatim in those instructions was the final step: "... Allrighty, time to load it. But before that, shut down all audio apps (including firefox). Once done, do this: sudo alsa force-unload sudo modprobe snd-whatever-module-you-need sudo modprobe snd-aloop ..." I was unsure about "snd-whatever-module-you-need" so I decided to just reboot. When KDE was just about to kick in, I saw a lot of new text I had never seen before scroll past very, very fast. Then it stopped and I could see it had something to with ALSA, but I couldn't really read anything. KDE started and... now I have no sound. I checked kmixer, it looks normal. It doesn't seem to be mute. I ran alsamixer in the command line, it doesn't seem to be mute either. I ran Kcontrol and checked the audio section, couldn't figure anything out. Here is the output of lsmod BEFORE the upgrade: $luc> lsmod | grep snd snd_hda_intel 434100 6 snd_pcm_oss 46336 0 snd_mixer_oss 22656 2 snd_pcm_oss snd_pcm 83076 3 snd_hda_intel,snd_pcm_oss snd_seq_dummy 10756 0 snd_seq_oss 37760 0 snd_seq_midi 14336 0 snd_rawmidi 29696 1 snd_seq_midi snd_seq_midi_event 15104 2 snd_seq_oss,snd_seq_midi snd_seq 56880 7 snd_seq_dummy,snd_seq_oss,snd_seq_midi,snd_seq_midi_event snd_timer 29704 3 snd_pcm,snd_seq snd_seq_device 14988 5 snd_seq_dummy,snd_seq_oss,snd_seq_midi,snd_rawmidi,snd_seq snd 62756 18 snd_hda_intel,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_seq_oss,snd_rawmidi,snd_seq,snd_timer,snd_seq_device soundcore 15200 2 snd snd_page_alloc 16904 2 snd_hda_intel,snd_pcm Here is the output of lsmod AFTER the upgrade: $luc> lsmod | grep snd snd_hda_codec_realtek 226308 1 snd_hda_intel 35840 3 snd_hda_codec 100992 2 snd_hda_codec_realtek,snd_hda_intel snd_hwdep 15364 1 snd_hda_codec snd_pcm_oss 46112 0 snd_mixer_oss 23040 3 snd_pcm_oss snd_pcm 85636 3 snd_hda_intel,snd_hda_codec,snd_pcm_oss snd_seq_oss 36224 0 snd_seq_midi_event 15232 1 snd_seq_oss snd_seq 57584 5 snd_seq_oss,snd_seq_midi_event snd_timer 29320 2 snd_pcm,snd_seq snd_seq_device 15372 2 snd_seq_oss,snd_seq snd 69412 14 snd_hda_codec_realtek,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_seq_oss,snd_seq,snd_timer,snd_seq_device soundcore 15200 3 snd snd_page_alloc 17032 2 snd_hda_intel,snd_pcm Looks like I have lost snd_seq_dummy, snd_seq_midi and snd_rawmidi. I don't need midi, so I just tried to load snd_seq_dummy with modprobe. The module is not found. I rebooted another two times hoping to be able to read something in that new boot sequence text, but I don't see it anymore. It's gone. I don't know what else to do. I can't go back to the backup modules, they are useless without /usr/include/sound which the installation method erased and nobody warned me it would.
