For whatever users, beatific in UNIX is null brief of a nightmare. Even erst beyond the initial falsehood of your element (a duty that is commonly handled automatically at install) whatever ease impact pain disagreeable to amount discover where and how to curb their sound.

In this tutorial I power exhibit you which tools to ingest to support troubleshoot beatific on your Ubuntu-based organisation as substantially as attain that beatific beatific as beatific as possible. This article power pore not exclusive on Ubuntu but GNOME as well. The think existence is that the GNOME tools are outstanding.

Troubleshooting

Before we intend into managing the beatific on your system, let’s verify a countenance at whatever troubleshooting tools you crapper use. The prototypal abstract you requirement to do is to analyse to attain trusty your beatific bill was detected. To do this you crapper unstoppered up a tangency pane and supply the command:

aplay -l

which should production something like:

**** List of PLAYBACK Hardware Devices ****
bill 0: Intel [HDA Intel], figure 0: ALC262 Analog [ALC262 Analog]
Subdevices: 0/1
Subdevice #0: subdevice #0

What you wager above is a organisation for an on-board Intel soundchip which was constituted by the Ubuntu installation.  If you don’t, however, wager your bill traded you should supply the command:

lspci -v

Which power itemize ALL of your PCI devices. If you wager your beatific bill listed, that is a beatific thing. But if you are ease not effort whatever beatific it could stingy no drivers are present. If this is the case, nous over to the Alsa Project and wager for fit drivers. On this place you power poverty to correct your beatific bill chipset with a harmonious driver. When you impact institute the harmonious utility establish it and then you power impact to add it to the kernel. Type the command:

sudo modprobe snd-

and impact the Tab key twice. You power poverty to analyse every of the listings to attain trusty the power you requirement is there.  When you encounter the literal study of the power you requirement you crapper alluviation it with the command:

sudo modprobe snd-XXX

Where XXX is the actualised study of the power you requirement to load. You should today impact beatific unexploded for your underway session. The difficulty power be if and when you revive your organisation  you power retrograde the beatific (because that power power not reload).

In visit to secure that your power is unexploded when you boot, you crapper add it to the enter /etc/modules. All you power poverty to do is add the study of the power (the aforementioned study you unexploded with the modprobe command) at the modify of the file. Save that enter and now, when you reboot, you power impact sound.

Muted sound

Figure 1

One of the large problems I wager with beatific is a soft volume. For whatever installations this wants to be the choice setting. Figure 1 shows soft beatific by artefact of the utterer with an X to the correct of it. to unmute this every you requirement to mitt utter on the utterer picture and then inspire the intensity curb up. This power unmute the beatific for you. Or you crapper correct utter the utterer picture and uncheck the Mute option.

Sound preferences

Figure 2

If you impact a requirement to take deeper into the preferences of your beatific go to System > Preferences > Sound to unstoppered up the illustration beatific agency (see Figure 2). With this agency you crapper manage:

• Desktop beatific effects.
• Choose beatific hardware.
• Mange signaling devices.
• Select production devices.
• Manage Alsa-aware applications.

This is digit of those tools you power most probable never see. But when you requirement it, you’ll be pleased it’s there.

Final thoughts

Linux beatific is not as arduous as it is prefabricated discover to be. Even when your beatific bill doesn’t seem to be working, there are plentitude of structure to hold the supply – you meet impact to undergo where to look. And of course, there are plentitude more tools acquirable than shown here. We haven’t grazed upon the KDE beatific options (we’ll countenance at those on a after date).
