[Alsa-user] Alsa virtual device
I am looking for a reference/example to do the following - I have a program with audio output that cannot be redirected/piped to another program from the command line. This program (Kodi) allows me to select the alsa device the sound stream is directed to. I wish to to split a stereo stream into six channels (three for the right and three for the left channel) and apply dsp (probably using ecasound) processing to each channel. Basically my left and right speakers each will have a three way electronic dsp crossover. I have heard comments that this can be done by defining a virtual (loopback?) alsa device. Is there any good reference/example on how to do this. Specifically how does the output of the virtual device get sent to the software? Thank you for any advice you can give me. -- Announcing the Oxford Dictionaries API! The API offers world-renowned dictionary content that is easy and intuitive to access.

[Alsa-user] Speaker-Test Tone Duration
I am using alsa speaker-test to set my channel gain levels with a spl meter and alsamixer one channel at a time. If I run the follow command line - speaker-test -Dhw:PCH -c 6 -s 1 everything works fine and I hear pink noise from the front left speaker, but the tone doesn't last long enough to set the channel gain using my spl meter. Is there anyway to make the duration of the tone (pink noise) longer. Fifteen seconds would be sufficient. -- ___ Alsa-user mailing list Alsa-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/alsa-user
[Alsa-user] Master Volume Control on Xonar Sound Cards
First, I have a Xonar D2 sound card. It does not have a separate master volume control in the alsamixer. If I use amixer with the 'Master' option the volume of each individual channel goes up or down depending on whether I execute amixer -c 1 sset Master 1+ & or amixer -c 1 sset Master 1- & The problem with this arrangement is that if the master volume in the command is set too high the relative volume setting between the channels is lost. Is there an alsa application that can change the overall volume in this case while maintaining the relative volume setting between the channels. Second, for a Xonar Essence STX/STX II with H6 daughter board is there a separate (hardward) master volume control in alsamixer and also if a headphone is plugged into headphone input of the main board is the 7.1 output (rca jacks) of the daughter board muted?

[Alsa-user] Using alsa loopback with surround sound
I am trying to capture surround sound with the alsa loopback device. I have configured the loopback device as sound card 0. I have no .asoundrc file. I am testing the loopback device with ecasound and kodi. I start ecasound (I do not know if this an ecasound or an alsa question) with the following command - brombo@TV:~$ ecasound -i alsahw,0,1 -o alsahw,2,8 ** *ecasound v2.9.1 (C) 1997-2014 Kai Vehmanen and others ** (eca-chainsetup) Chainsetup "untitled-chainsetup" (eca-chainsetup) NOTE: Real-time configuration, but insufficient privileges to utilize real-time scheduling (SCHED_FIFO). ... With small buffersizes, this may cause audible glitches during processing. (eca-chainsetup) "rt" buffering mode selected. (eca-chainsetup) Opened input "alsahw", mode "read". Format: s16_le, channels 2, srate 44100, interleaved. (eca-chainsetup) Opened output "alsahw", mode "write". Format: s16_le, channels 2, srate 44100, interleaved. - [ Connected chainsetup: "untitled-chainsetup" ] - [ Controller/Starting batch processing ] --- - [ Engine - Driver start ] -- ^C- [ Controller/Batch processing finished (0) ] --- - [ Engine exiting ] - (eca-control-objects) Disconnecting chainsetup: "untitled-chainsetup". brombo@TV:~$ alsahw,0,1 is the loopback capture device and alsahw,2,8 is a hdmi output. The ecasound command is executed before I start kodi. I select the loopback audio device in the kodi audio setup menu. This gives me sound, but only in stereo, even if the source is 5.1 channels. If I select the hdmi output in the kodi audio setup I get 5.1 channel output. Do I need to force the loopback device to use 6 channels. If so how do I do it? Is there another problem?

[Alsa-user] Understanding Audio Device Mappings
Running ubuntu 14.04. Attached is the output from aplay -Ll and arecord -Ll for my computer. If select loopback as the sound card and execute - ecasound -i alsahw,0,1,0 -o test.wav I can capture the audio output of a running application to the wave file. What is not clear is what devices defined by alsahw,i,j,k I should use for 5.1 surround in the loopback sound card and in the analog output sound card. If I look at aplay.txt I see an entry - surround51:CARD=PCH,DEV=0 HDA Intel PCH, ALC1150 Analog 5.1 Surround... I know that i=1 and j=0, but what k to use for surround51.

[Alsa-user] Playing analog input with volume control
I am running Ubuntu 14.04. I am trying to play the output (amplified to line level) of a turntable through my computer with a volume control that works. The audio output of the computer is via an Nvidia hdmi to a surround sound preamp. The input is the analog line in connection of a Xonar D2 sound card (eventually the D2 will replace the surround sound preamp). I can play the records with either of the below commands - built-in: | pactl load-module module-loopback | or, try ecasound: | sudo apt-get install ecasound ecasound -i alsa -o alsa | but I cannot control the volume. Since I wish to control the volume via the multimedia volume keys on my keyboard what are the appropriate command line inputs or script to accomplish this.
