Libusb.org Sound Cards & Media Devices Driver Download

Posted on

So im creating this thread for people to list capture cards that are known to work not in obs only but like if it works in VLC perfectly fine then try to get the name of it followed by a link were people can purchase it if they want to makes it easier for everyone i will start this August vgb. Even the transmitter circuits can operate differently since there’s no standard for output voltage. I believe this has held back advancement of inexpensive zero-IF designs since using a sound card complicates sharing of experiment results.!! The Peaberry SDR V2 is designed to solve the sound card problem. It includes a DAC/ADC that is.

BurnInTest Linux users guide: 4.0: 1.2 MB: Contains the same information as the help file (which comes with the software download) but is in a more readable PDF format. Auxiliary Tools apt-get install build-essential libusb-1.0 libusb-1.0-0-dev sudo apt-get install smstools Downloads: 3 This Week Last Update: 2018-11-02 See Project 21. I think it would be highly unusual for the libusbsetinterfacealtsetting call itself to cause the SIGSEGV. I would expect that either a prior call would cause this, or the SIGSEGV is an indirect effect of the call. That is, this call changes the alternate setting, which effectively starts the transfer of audio data.

Raspberry Pi Broadcastify Feed Appliance

These instructions show you how to purchase and setup a completely self contained Raspberry Pi to broadcast a live audio feed to Broadcastify.com

These instructions have been verified and tested as working on a Raspberry Pi 2 Model B Project Board - 1GB RAM - 900 MHz Quad-Core CPU. Also installed and working on a Raspberry Pi 3 Model B (1 GB RAM - 1.2GHz 64 bit Quad-Core CPU - built in 802.11n wireless).

Purchase Equipment

Raspberry Pi 2 Model B Project Board

-or-Raspberry Pi 3 Model B+ Project Board

-or-Raspberry Pi 3 Model B+ Kit, includes power supply, case, heat sinks, in-line power switch (recommended)

Power Supply with in-line switch for Raspberry Pi

Memory Card for Raspberry Pi

Case for Raspberry Pi (optional)

Inexpensive USB sound card ($9)

1/8 inch audio cable to connect scanner to USB sound card

Install Raspbian OS

All testing and configuration was done using Raspbian

  • Follow the instructions here to install the OS on the memory card you purchased:

Install pre-reqs and update raspberry pi to latest version

Configure the Sound Card

  • Plug your scanner's headphone jack into the mic jack on the USB sound card dongle
  • Start alsamixer
  • press F6, choose the 'USB Headphone Set' entry
  • press your tab key to select the 'Capture' device volume control
  • use your 'up arrow' key to adjust the level to it's lowest level possible (6)
  • press escape to exist alsamixer
  • run the following command to save the volume settings

Two Choices of Software to Broadcast

We recommend the darkice install and configuration method

Method 1: Darkice Install and Configuration (Recommended)

  • download the precompiled version of darkice
  • uncompress the files
  • move the files to the proper places and make sure they are executable
  • Edit the /etc/darkice1.cfg file to match your settings, including the sound card you are using, your feed server, mount, password, and description, then exit and save the file
  • Enable the feed to start broadcasting at boot
  • Start your feed

Method 2: Ezstream Install and Configuration

Create the following configuration file at /etc/ezstream_bcfy.xml and replace with your mount, password, and stream name. If you plan on having multiple streams make sure and create a separate named configuration file (i.e.'/etc/ezstream_bcfy2.xml) for each stream and reference accordingly in your command script below.

  • Run this command to start the sound card broadcast

Note: very little volume will be needed from your scanner - adjust the levels as appropriate for a good sounding feed.


Optional Scripts

  • Discussion: Script to alert feed owner to high number of listeners Thread


Troubleshooting

Clicking sound in the audio stream

If your stream has a clicking sound when there is no audio, you may be able to eliminate it by turning off Auto Gain Control.

  • Start alsamixer
  • Press F6 and select your audio device
  • Press Tab to select 'Auto Gain Control'
  • Press the 'm' key to toggle it off
  • Press Escape key to exit alsamixer
  • Save your settings with the following command

Darkice not working or not starting on boot

The procedure above for starting the darkice service on boot does not seem to work on Raspbian Buster Lite (version: July 2019). This is due to newer versions of Raspbian implementing service management via systemd. It's possible to get it working using Raspbian Stretch and a crontab. Drivers mingwah aohan high card reader.

Instead of following the instructions to install the latest version of Raspbian, install the Stretch version:

  • Download the image here: 2019-04-08-raspbian-stretch-lite.zip, or use the non-lite version if you want the GUI.
  • Use Balena Etcher or similar to flash it onto your SD card
  • Enable SSH (optional) by adding a blank file named 'ssh' to the SD card
  • Use raspi-config to set your timezone and expand the filesystem if necessary
  • reboot and follow the steps above, starting with 'apt-get update', and stopping after editing your /etc/darkice1.cfg file


Set up 'screen' and use it to run darkice in a detached screen, where it will keep running even if you close your terminal.

  • Install screen
  • run darkice in a screen, specifying your config file

At this point, you should be able to confirm that darkice is running, and streaming your audio.


Now, set up a cron tab to automatically restart things after every reboot.

  • Edit or start your cron file.

If it tells you there's no cron file, let it create one. Choose option 2 for the nano editor.

  • add the following line to the bottom of your cron file:

This runs after every reboot. It waits 30 seconds (to allow your network and other requirements to finish loading), and then starts a screen with darkice, using your config file.

Reboot and check that darkice is running:

The two ps commands should each return a line showing that screen and darkice are running. Your audio should now start streaming about 30 seconds after each reboot.
