Hi, I'm trying to set up Alsa on my Arch linux system. I'm following advices from Arch wiki: https://wiki.archlinux.org/index.php/Advanced_Linux_Sound_Architecture My desctop environment is Window Maker. I started X Window with startx command. I have two sound cards on this machine: the NVidia sound card and the USB webcam's sound card ( here is the microphon that I want to use eg. for recording my desktop or some window to make tutorials ). What I did sofar are: run asoundconf-gtk and get the file: ----------------------------------------- ~/.asoundrc.asoundconf by asoundconf-gtk ---------------------------------- ~/.asoundrc pcm.!default { type plug slave.pcm { @func getenv vars [ ALSAPCM ] default "hw:NVidia" } } --------------------------------- /etc/asound.conf pcm.!default { type plug slave.pcm { @func getenv vars [ ALSAPCM ] default "hw:NVidia" } } ctl.equal { type equal; } pcm.plugequal { type equal; # Modify the line below if you do not # want to use sound card 0. #slave.pcm "plughw:0,0"; # by default we want to play from more sources at time: slave.pcm "plug:dmix"; } # pcm.equal { # If you do not want the equalizer to be your # default soundcard comment the following # line and uncomment the above line. (You can # choose it as the output device by addressing # it with specific apps,eg mpg123 -a equal 06.Back_In_Black.mp3) pcm.!default { type plug; slave.pcm plugequal; } Uninstall any pulse package except: libao libpulse lib32-libpulse These can't be purged because of dependencies with other applications ( like xulrunner, etc. ). When I start audacity, I get error message: ALSA lib pcm.c:2239:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.rear ALSA lib pcm.c:2239:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.center_lfe ALSA lib pcm.c:2239:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.side ALSA lib pcm_route.c:947:(find_matching_chmap) Found no matching channel map ALSA lib pcm_route.c:947:(find_matching_chmap) Found no matching channel map ALSA lib pulse.c:243:(pulse_connect) PulseAudio: Unable to connect: Connection refused ALSA lib pulse.c:243:(pulse_connect) PulseAudio: Unable to connect: Connection refused Failed to load plugin "/usr/lib/ladspa/caps.so": /usr/lib/ladspa/caps.so: cannot open shared object file: No such file or directory Whe I run Qt-recordmydesktop I can't record my voice. What must I do to solve these problems?
