i follow instruccionts of https://help.ubuntu.com/community/DebuggingSoundProblems Checking volume levels from command line (all Ubuntu versions) 1. Open a terminal window 2. Launch alsamixer 3. Make sure sound is unmuted and that the volume is turned up. Unmute everything. Sometimes a muted channel will be the problem, even if the description doesn't seem immediately relevant. all good (...) cat /proc/asound/cards only one card...

From there, you can test the different options. In some scenarios several different sound servers may be installed, and only one may work. This is probably the origin of the problem if you cannot play audio with xine or rhythmbox, but you can with xmms or helix/realplayer. Any of these works * If you have no sound and you have a regular sound card type "lsmod | grep snd" in the terminal and see if there is more than one card listed. It's possible that you have a motherboard sound chip that is interfering. Add it to the bottom of the blacklist file. For example, sudo nano /etc/modprobe.d/blacklist then add "blacklist snd_via82xx" to the bottom. it seems i only have one (is a notebook) and modules whit snd are snd_hda_intel, and software ouputs, no? lsmod | grep snd snd_pcm_oss 38912 0 snd_mixer_oss 14784 1 snd_pcm_oss snd_hda_intel 257272 1 snd_pcm 69828 2 snd_pcm_oss,snd_hda_intel snd_timer 19556 1 snd_pcm snd 44836 7
