To clarify, lightshowpi will not see it as an audio source.

I've had everything working and decided to purchase a USB sound card so I could plug my iPod or computer into the mic slot. I get the lights working fine but it no longer plays any sound. I've tried both the sound card and the on board aux out.

I can record the input with arecord fine and can play it back fine but lightshowpi doesn't seem to output any sound anymore.

Testing is complete! i have a RPi connected to an 8 channel relay which is connected to 8 individual outlets. When I plug in my lights into the outlets and they default to on and when it is their turn to blink they blink off. how do i switch this to default to off and swith on when it is their turn. I thought I saw something on here earlier but I cant find it currently. Any help is appreciated! thanks!

Hello,
i'm just love the idea of the project so i wanted so stream to my pi.
I decided to test it out with a southcast stream, and it worked perfektly - but after around 30 secs it starts to lag extreme.
Its a pi 3 and i streamed via ethernet.
i wouldnt even need pi audio output - may there is a way to just let them light up but not playing the sound?
May you can give me some advice?
Thanks ib4

Greetings fellow LightshowPi users!  Got my B2+ all set up and running, and have built a small display box.  Now, I have been using playlist mode so far, but now I want to use a line level input from my home audio system.  I have un-commented the line in the config file for mode=audio-in.  I have purchased a Sabrent AU-MMSA USB audio card which according to their website requires no drivers.

     According to wiki.linuxaudio.org/wiki/raspberrypi#setting_the-default_soundcard, if I look at /etc/modprobe.d/alsa-base.conf,I make changes to allow the USB audio card to be the default.  Unfortunately I do not any entry under modprobe.d with that name.  The same reference doc states that I can remove the kernal module for the onboard soundcard from /etc/modules, but the only entry I have in modules.conf is i2c-dev.

     Obviously I am missong something here, but not being experienced in Python, I don't know what!

     Thank you for any and all help.

THANK YOU TOM!!  When I read the config file, I saw that entry under the heading of audio_out_card_configuration, but did not realize that it was going to be needed in the audio_in mode as well.  Works great, again, Thank you for your assistance.

Hello again. If someone could help me with this, it would be amazing. I do not know how to manually program the lights to where they set off at the time I want them to. Could someone redirect me or give me some tips with this? It would be a lifesaver! Thanks
Regards,
Matthew

That's not really lightshowpi, "our software automates the creation of a lightshow using the frequency spectrum of the song that is playing back"

You might use custom_channel_mapping to get a little control of it, but lightshowpi was never meant for that much control. 

Another option ist to try and edit the sync files, but that was not something that was accounted for either.

I think it's really awesome that the hardware is driving software efforts at this point. It's often the other way around :) But yeah, love Arch Arm

Hello all!
i was playing with the Tom_Slick version with WebUI when i completely messed up the configs. So i decided to completely reinstall and now im getting this when launching the service:

Job for lightshowpi-web.service failed. See 'systemctl status lightshowpi-web.service' and 'journalctl -xn' for details.

and this from the journal:
-- Unit lightshowpi-web.service has begun starting up.
Jul 18 01:53:45 raspberrypi systemd[628]: Failed at step EXEC spawning /py/lightshowpi_daemon.py: No such file or directory
-- Subject: Process /py/lightshowpi_daemon.py could not be executed

I have since completely wiped the sd card and re-imaged with jesse-lite and re-installed but getting the same error... i have to finish rebuilding by thursday night, if anyone can help, that would be great!

no thank you for the incredible level of support
i was able to get the show running (with a reboot every few songs) in time for the party
i also found out that there was a contest (probably why my mother was so adamant about getting the show going... but yea, we won second place, and only because you worked the issues with me and i was able to get it going an hour before the party
needless to say i will be taking a week or so off for lightshow setup but will be back at it soon to work out all the bugs for another party end of august, and then Halloween!

Thanks again and again - couldn't have done it without your support

PiFM - anyone notice a slight delay in the audio? everything is fine with the audio out, but with piFM there seems to be a .5 - 1 second delay in the audio. tried on both my pi2's, one has wheezy and the other jesse lite

is there a way to adjust either the lightshow or the audio, as in intentionally add a delay to the one that is ahead?

FM would be the best solution for my "Mom Proof" build as the magic of the show would stay in the box :-P but i can add a headphone jack to the build if necessary... just curious

Sorry for the book worth of text, but i have a challenge for those willing...

Here we go again, this time for my mother. So, instead of tinkering my way through getting a show going (which I thoroughly enjoyed last year) I would like to ask the community for the best (not necessarily easiest) way to implement an 8 SSR show setup. And as bulletproof as possible... Like seriously, my mom corrupted 2 SD cards last year by hard shutdowns

I'm looking for the best OS and configuration you guys recommend and the kind of ease of use my severely computer illiterate mother will be able to use and not break. Last year I set her up with a simple ssh button app that allowed her to hit one button to start and another to stop.

This year I was going to consider the SMS functionality (if that is still a thing) and I heard you can use the SD card for boot only and the running software on a USB storage device... Which helps cut down on the corruption issues... Anyone have experience with that?

I have about a month to play before the Xmas in July party she is hoping I will have this done.

I should probably mention, I have a couple pi2 model B's

Thanks in advance

What changes need to be made to Lightshowpi for the mic to work. I have the audio from the usb to the speakers working. But the the audio to the mic is not working or streaming. It just plays the sample music when you use command synchronized_lights.py. Also changed the file defaults.cfg for audio_in. I'm running on a PI2

In the config you will need to change 2 setting

[lightshow]
mode = audio-in
audio_in_card = default

For the value of audio_in_card you need to find the name of your input device

Unplug your usb sound card
At the command prompt type
aplay -L | grep sysdefault

Note the devices listed
Now plug your usb sound card back in and run the same command
aplay -L | grep sysdefault

You will see a new enter that is your sound device.
Use that for audio_in_card
example
audio_in_card = sysdefault:CARD=Device

Having fun with my new lightbox, and now have a question/problem?  Because I am going to leave my Pi dedicated to lightshow, is there some way to have the program autostart at power-up?  If I was still using windoze, I could just change the autoexec.bat file, but raspbian doesn't have one of those!  :-)

Thanks

No worries, The daemon should work (haven't tested it). Cron has an option @reboot that executes the job on boot so you have two options.

That's strange. gcc is not installed

use this to install
sudo apt-get install build-essential

then try the lightshowpi installer again

Hello! I am a new Pi user and I want to use LightShowPi for a university project. I followed the install instructions on the official site and the installation was successful. When I tried to reboot (it was advised after the installation) I faced a new for me screen. Blank screen with a blinking underscore. After some search I realised that I need to press Ctrl+Alt+F2 to get to login. Till now when I was powering up the Pi it was always getting me to the desktop without prompting for login. After I logged in with the default user/pass and typed startx I was getting a blank screen. The only workaround I found was to type sudo startx and then it would boot up normally (logged in as root :S). Since the Pi is new I didn't hesitate and formatted my SD card in case I did something wrong during installation. I tried installing LightShowPi again following the same steps as before and had the same results. Any help would be appreciated. Thanks.

So, I'm up and running :-) , I've had a play with both VNC and SSH as the method of accessing the Pi. 
I found a tutorial online that showed how to use your phone as a wifi hotspot for the Pi (useful as my setup is going to be mobile so no home router available). Of course, numpty here forgot to bookmark the page and now I can't find it again.
Does anyone have a link to a guide ?

Is this what you are looking for?  It's a few years old:

http://www.daveconroy.com/how-to-tether-your-raspberry-pi-with-your-iphone-5/

I'm not sure why you can't just use the graphical interface to tell it the details to connect to your iPhone.  Then, you can use raspi-config to switch to text console login, and it will remember the WiFi configuration.

I've done this for both an RPi 2 and a RPi Zero.  Actually, I set up the micro SD card on my original RPi 2 with the desired WiFi dongle, then just moved the SD card and the dongle to the new RPi.  They recognize my home WiFi, and connect.  Then I use SSH from my MacBook to connect.

Setting up your phone as a WiFi hotspot will depend on your phone, and even your cellular service.  Some cell service plans don't allow "tethering".
