[Note]

Note

The ALSA Tools package has not been tested by the BLFS editors.

Package Information

ALSA Tools Dependencies

Required

ALSA Library-1.0.13

Optional

pkg-config-0.20 and GTK+-2.8.20 or GTK+-1.2.10 (to build echomixer, envy24control and rmedigicontrol), FLTK (to build hdspconf and hdspmixer), and Qt-3.3.7 (to build qlo10k1).

Installation of ALSA Tools

The ALSA Tools package is only needed by those with advanced requirements for their sound card. The tools are not all built together, instead you need to cd into the directory of each tool you wish to compile and run the following commands: 

./configure --prefix=/usr &&
make

The ac3dec tool comes with a test suite, but it is not functional since it does not contain the reference results for the dither_test program.

Now, as the root user: 

make install

Short Descriptions

ac3dec

is a free AC-3 stream decoder.

extract_ac3

will take an MPEG-2 stream and produce AC-3 audio to stdout if it exists.

as10k1

is an assembler for the emu10k1 DSP chip present in the Creative SB Live, PCI 512, and emu APS sound cards. It is used to make audio effects such as a flanger, chorus or reverb.

echomixer

is the Linux equivalent of the Echoaudio console application from Echoaudio. It is a tool to control all the features of any Echoaudio soundcard. This includes clock sources, input and output gains, mixers, etc.

envy24control

is a control tool for Envy24 (ice1712) based sound cards.

hdspconf

is a GUI to control the Hammerfall HDSP Alsa Settings. Up to four hdsp cards are supported.

hdsploader

is used to load the firmware required by the Hammerfall HDSP sound cards.

hdspmixer

is the Linux equivalent of the Totalmix application from RME. It is a tool to control the advanced routing features of the RME Hammerfall DSP soundcard series.

ld10k1

is the server of a EMU10K{1,2} patch loader for ALSA.

lo10k1

is the client of a EMU10K{1,2} patch loader for ALSA.

dl10k1

loads config dumps generated by lo10k1 and ld10k1.

ld10k1d

is an init script for the ld10k1 patch loader.

qlo10k1

is a Qt GUI for the ld10k1 patch loader.

mixartloader

is a helper program to load the firmware binaries onto the Digigram's miXart board sound drivers. The following modules require this program: snd-mixart. These drivers don't work properly at all until the certain firmwares are loaded, i.e. no PCM nor mixer devices will appear.

pcxhrloader

is a helper program to load the firmware binaries onto Digigram's pcxhr compatible board sound drivers. The following modules require this program: snd-pcxhr. These drivers don't work properly at all until the certain firmwares are loaded, i.e. no PCM nor mixer devices will appear.

rmedigicontrol

is a control tool for RME Digi32 and RME Digi96 sound cards. It provides a graphical frontend for all the sound card controls and switches.

cspctl

is an SB16/AWE32 Creative Signal Processor (ASP/CSP) control program.

sbiload

is an OPL2/3 FM instrument loader for the ALSA sequencer.

sscape_ctl

is an ALSA SoundScape control utility.

us428control

is a Tascam US-428 control program.

usx2yloader

is a helper program to load the 2nd Phase firmware binaries onto the Tascam USX2Y USB sound cards. It has proven to work so far for the US122, US224 and US428. The snd-usb-usx2y module requires this program.

vxloader

is a helper program to load the firmware binaries onto the Digigram's VX-board sound drivers. The following modules require this program: snd-vx222, snd-vxpocket, snd-vxp440. These drivers don't work properly at all until the certain firmwares are loaded, i.e. no PCM nor mixer devices will appear.
