Yes, the mixer is avaible, but appears in "mute" mode, and when i tried to change the volumen levels, appears this error:
Volume control cant find devices to control. You dont have the correct addons of Gstreamer or sound device configurated The applicactions works fine, and i can play music but the speakers are muted. I get tired of alsa, and i just change my repository list to testing, update the system, and everithing works again, i have sound again. But i take this commands before the update, maybe can help: And this is my forum post when we tried to solve the problem: http://forums.debian.net/viewtopic.php?f=7&t=65686 alsactl init > Unknown hardware: "HDA-Intel" "Realtek ALC887" > "HDA:10ec0887,1458a002,00100302" "0x1458" "0xa002" > Hardware is initialized using a guess method > /usr/share/alsa/init/default:26: control element not found > /usr/share/alsa/init/default:26: control element not found > /usr/share/alsa/init/default:41: control element not found > > lsmod | grep snd > snd_hda_codec_realtek 252147 1 > snd_hda_intel 18323 0 > snd_hda_codec 65511 2 snd_hda_codec_realtek,snd_hda_intel > snd_hwdep 5492 1 snd_hda_codec > snd_pcm 61312 2 snd_hda_intel,snd_hda_codec > snd_seq 43041 0 > snd_timer 15646 2 snd_pcm,snd_seq > snd_seq_device 4717 1 snd_seq > snd 46912 8 > snd_hda_codec_realtek,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_pcm,snd_seq,snd_timer,snd_seq_device > soundcore 4598 1 snd > snd_page_alloc 6185 2 snd_hda_intel,snd_pcm dpkg-query -l alsa* > Deseado=Desconocido/Instalar/Eliminar/Purgar/Retener > | > Estado=No/Instalado/Config-files/Desempaquetado/Medio-conf/Medio-inst/espera-disparo/pendiente-disparo > |/ Err?=(ninguno)/Requiere-reinst (Estado,Err: mayúsc.=malo) > ||/ Nombre Versión Descripción > > +++-==============-==============-============================================ > un alsa <ninguna> (no hay ninguna descripción disponible) > ii alsa-base 1.0.23+dfsg-2 ALSA driver configuration files > ii alsa-modules-2 1.0.23+dfsg-2+ ALSA modules for kernel 2.6.32-5-amd64 > ii alsa-oss 1.0.17-4 ALSA wrapper for OSS applications > ii alsa-source 1.0.23+dfsg-2 ALSA driver sources > ii alsa-utils 1.0.23-3 Utilities for configuring and using ALSA > > No sound whit this commands: speaker-test > speaker-test -c2 > speaker-test -c2 -twav > sudo alsamixer cannot load mixer controls: Argumento inválido
