Some machines, (like the Dell E6400) may also require the Front and Headphone channels to be unmuted and adjusted.

Some machines, (like the Thinkpad T61), have a Speaker channel which must be unmuted and adjusted as well.

For the Soundblaster Audigy LS mute the channel labeled IEC958.

Some cards need to have digital output muted or disabled in order to hear analog sound.

If your system has more than one soundcard, then you can switch between them by pressing F6.

If that does not work, consult the #Configuration section or the /Troubleshooting page. $ aplay -L | grep :CARD default:CARD=PCH # 'default:PCH' is the PCM channel name for -D D accepts PCM channel names as values, which can be retrieved by running the following: If audio is being outputted to the wrong device, try manually specifying it with the argument -D. See /Troubleshooting#Microphone if microphone does not work.Д¬hange -c to fit your speaker setup. To enable your microphone, switch to the Capture tab with F4 and enable a channel with Space. In order to accomplish that, see #Upmixing/downmixing. Note: Please take note that this will not automatically upmix stereo sources (like most music). The gain can be found in the upper left next to the Item: field. Use the в†‘ key to increase the volume and obtain a value of 0 dB gain.

Scroll to the Master and PCM channels with the в†ђ and в†’ keys and unmute them by pressing the m key. The MM label below a channel indicates that the channel is muted, and OO indicates that it is open. Unmuting the sound card can be done using alsamixer: Unmuting the sound card's master volume can be done by using amixer:

Sof-firmware and/or alsa-ucm-conf are required for some newer laptop models (mainly since 2019) because they implement their drivers with firmware provided by the Sound Open Firmware project.Д«y default ALSA has all channels muted. The alsa-firmware package contains firmware that may be required for certain sound cards (e.g. You can check their status using systemctl. To edit these units, see systemd#Editing provided units. You can decide for one of the two approaches depending on your requirements. rvice (Re-)Starts alsactl in daemon mode to continuously keep track of, and persist, volume changes, under the condition that the user has consciously created /etc/alsa/nf.Д®vidently, both methods are mutually exclusive.As /etc/alsa/nf is not created without a conscious action of the user, it is the default method. rvice Reads /var/lib/alsa/asound.state on boot and writes updated values on shutdown, provided /etc/alsa/nf does not exist.These are automatically installed and activated during installation (via package provided symlink to sound.target). The alsa-utils package comes with systemd unit configuration files rvice and rvice by default. $ apulse yourapplication ALSA and systemd Then load the snd-seq-oss, snd-pcm-oss and snd-mixer-oss kernel modules to enable OSS emulation.ДЄpulse AUR lets you use ALSA for applications that support only PulseAudio for sound.

If you want OSS applications to work with dmix, install the alsa-oss package as well. Without OSS or the emulation library, /dev/dsp will be missing, and the application will not produce any sound. for legacy applications which try to open /dev/dsp and write sound data to them directly. Note: This is important if your application complains about missing /dev/dsp or /dev/snd/seq.ДЄLSA has some ability to intercept OSS calls and re-route them through ALSA instead. To allow remote users to use ALSA, you need to add those users to the audio group, however this is not recommended by default (see note below). Usually, local users have permission to play audio and change mixer levels. However, your sound may be initially muted. Udev will automatically detect your hardware and select needed drivers at boot time, therefore, your sound should already be working.
