Check that the audio playback program is unmuted/volume is raised, from inside the application, and in the system audio mixer (eg. PulseAudio volume control or alsamixer. 2. Check that your soundcard is visible, enabled, and is selected as default in the Configuration tab of the audio mixer Applications -> Sound & Video -> Pulseaudio volume control -> pavucontrol -> what is "Dummy output"? https://askubuntu.com/questions/800262/persistent-dummy-output https://askubuntu.com/questions/491346/how-do-i-get-my-sound-working lspci -vvv | grep -A8 Audio # (find-man "1 grep") # (find-man "1 grep" "-A NUM, --after-context=NUM") 3. Disable any other output devices like HDMI, only enable the desired output 4. Check that your soundcard is detected by ALSA: aplay -l # (find-man "1 aplay") # (find-man "1 aplay" "-l, --list-devices") aplay -l 5. Check that a driver/module is loaded for your sound card using lspci -knn # (find-man "8 lspci") # (find-sh "lspci -knn") # (find-sh "lspci -knn | grep -A2 Audio") lspci -knn lspci -knn | grep -A2 Audio 6. If not, identify your soundcard's PCI ID ([XXXX:XXXX]) and paste the ID here to determine if a driver is available in Debian. # (find-sh "lspci -knn | grep -A2 Audio" "8086:293e") # (find-sh "lspci -knn | grep -A2 Audio" "17aa:20f2") 7. Check if your soundcard requires an additional Firmware. 8. Check whether you can play sound as Root/add your user to the audio group groups 9. Check proper connection of the output jack 10. Check that your amplifier/speakers are powered on and working Wiki pages * (eepitch-shell) * (eepitch-kill) * (eepitch-shell) play -n -c1 synth sin %-12 sin %-9 sin %-5 sin %-2 fade h 0.1 1 0.1 sox play -n -c1 synth sin %-12 sin %-9 sin %-5 sin %-2 fade h 0.1 1 0.1 play -n synth 1 sine 440 play existing-file.wav ;# equiv to "sox existing-file.wav -d" rec new-file.wav ;# equiv to "sox -d new-file.wav" /etc/security/limits.d/audio.conf libjack-jackd2-0 38 apti jackd2 jack-tools Atari POKEY: http://asma.atari.org/ http://asap.sourceforge.net/ http://en.wikipedia.org/wiki/Speech_recognition_in_Linux http://en.wikipedia.org/wiki/CMU_Sphinx http://en.wikipedia.org/wiki/Julius_(software) http://en.wikipedia.org/wiki/List_of_speech_recognition_software http://shout-toolkit.sourceforge.net/ http://en.wikipedia.org/wiki/RWTH_ASR # (find-available "gstreamer0.10-plugins-good") # (find-zsh "availabledebs | sort | grep sphinx") # Local Variables: # coding: utf-8-unix # End:
