![]() If all fails, you may want to eliminate hardware failure by testing the microphone with a different device.įor at least some computers, muting a microphone (MM) simply means its input does not go immediately to the speakers. $ arecord -vvv -format=dat -device=plughw:0,0 /dev/null To test a particular device, use the -device parameter followed by the hardware PCM name in the form hw: C, D for card C device D, or plughw: C, D for plugged hardware. $ arecord -duration=5 -format=dat test-mic.wavĪlongside alsamixer to easily identify channel which you should select and unmute. To test the microphone, run these commands (see arecord(1) for further information): You may also need to enable and increase the volume of Line-in in the Playback section. Try making positive Mic Boost and raising Capture and Digital levels higher this may make static or distortion, but then you can adjust them back down once you are hearing something when you recordĪs the pulseaudio wrapper is shown as "default" in alsamixer, you may have to press F6 to select your actual soundcard first. Mic, Internal Mic) and/or on Capture (in alsamixer, select these items and press space). ![]() In alsamixer, make sure that all the volume levels are up under recording, and that CAPTURE is toggled active on the microphone (e.g. ![]() If you use MPD and the above configuration tips do not work, try following. If this is the case, try setting the default sound card. If you have no sound on startup, this may be because your system has multiple sound cards, and their order may sometimes change on startup. If there is no sound, you may see something similar to:ĪLSA lib pcm_dmix.c:1022:(snd_pcm_dmix_open) unable to open slave You can quickly test sound by running speaker-test. Checking the HP option under widget control in the Playback Switch (Node PIN in the ALC892 codec, for instance) can sometimes improve audio quality and volume significantly. Some audio codecs may need to have settings adjusted in the HDA Analyzer (see #Volume is too low) in order to achieve proper volume without distortion.Setting a high value for Pre-Amp can cause sound distortion, so adjust it according to the level that suits you.If you are facing low volume even after maxing out your speakers/headphones, you can give the softvol plugin a try. If the volume is still too low, run alsamixer again: resetting the codecs may have caused new sliders to become enabled and some of them may be set to a low value. $ wget -O hda-analyzer.py a=blob_plain f=hda-analyzer/run.pyĬlose the analyzer, and when prompted as to whether you want to reset the codecs, say "yes". If all the sliders are maxed out, and the volume is still too low, you can try running the following script to reset your codec settings: Note that if you have many sliders, you may have to scroll to the right to see any missing sliders. Run alsamixer and try to increase the value of the sliders, unmuting channels if necessary. If the problem persists, verify that the Auto-Mute option in alsamixer is set to Disabled. Alternatively, killing the PulseAudio process may cause sound to start working in the desired process. If it is, try using apulse AUR, as described in Advanced Linux Sound Architecture#PulseAudio compatibility. # Initialize memory (rev:3.If speaker-test produces sound but some other program does not, determine whether PulseAudio is being used: McdSlot 1 : /home/leandro/.config/PCSX2/memcards/Mcd002.ps2 McdSlot 0 : /home/leandro/.config/PCSX2/memcards/Mcd001.ps2 INFO: GL_ARB_get_texture_sub_image is available INFO: GL_ARB_texture_barrier is available INFO: GL_ARB_direct_state_access is available INFO: GL_ARB_vertex_attrib_binding is available INFO: GL_ARB_shader_storage_buffer_object is available INFO: GL_ARB_shader_image_load_store is available INFO: GL_ARB_sparse_texture2 is NOT SUPPORTED ![]() INFO: GL_ARB_sparse_texture is NOT SUPPORTED * * Track 1: Data (Mode 1) (2151344 sectors)ĮGL: Supported extensions: EGL_EXT_device_base EGL_EXT_device_enumeration EGL_EXT_device_query EGL_EXT_platform_base EGL_KHR_client_get_all_proc_addresses EGL_EXT_client_extensions EGL_KHR_debug EGL_EXT_platform_device EGL_EXT_platform_wayland EGL_KHR_platform_wayland EGL_EXT_platform_x11 EGL_KHR_platform_x11 EGL_MESA_platform_gbm EGL_KHR_platform_gbm EGL_MESA_platform_surfaceless * CDVD Disk Open: DVD, Single layer or unknown: IsoFile open ok: /home/leandro/games/playstation-2/isos/Shin Megami Tensei - Persona 4 (USA).iso ![]() Patches: No CRC found, using 00000000 instead.
