WaveInput for Linux

Hi, flushed with success in getting BBC iPlayer running (thank you) I now undertook WaveInput.

http://forums.slimdevices.com/showth...nput-for-Linux

This is a post from 2008, so probably a bit(!) dated, but I haven't found anything more current:

Summary
This plugin enables Linux PC audio to be streamed through SqueezeCenter.
Just exactly what I want, thank you.

Quote:

Install
Install by unpacking the attached .tar.gz file
Um, I do not see any "attached .tar.gz file"

I have installed the specified repo, and have installed the WaveInput plugin therefrom, but it doesn't work, so I suspect the available plugin may be a Windows version not the Linux version??

Define "it doesn't work":
• Activate the plugin in "Settings"
• Add a favorite WaveInput URL: wavin:default
• Stop, then start LMS
• Click WaveInput under Favorites
• It opens a right hand panel:
Name:  waveinput-50.jpg
Views: 7
Size:  44.6 KB
• Start the audio stream (e.g., Chromium, Audacity, whatever), observe sound from the computer speakers
• Observe the following in PulseAudio Volume Control (PAVC):
∘ Playback:
* ALSA Plugin [Audacity]: ALSA Playback on. Peaks at ~40dB
∘ Output Devices:
* Simutaneous Output to Built-in Audio Analog Stereo (BAAS). Peaks at ~33dB

• I click the play (>) button. It changes to the pause icon (two vertical bars) for a second, then changes back to the play icon.

Thanks again, Andy

The most difficult part in getting this plugin to work will probably be the ALSA configuration. Typically the user will use an appropriate mixer application (e.g. amixer, alsamixer, Kmixer, Gnome-alsamixer) to configure the correct stream to be used in playback.
I am using PulseAudio Volume Control (PAVC) as an interface between source applications (Chrome, mp3 players, Audacity, etc) and sink applications, such as Audacity for recording ALSA streams and of course LMS WaveInput, except it doesn't show up under PAVC.

All the source streams are manifested to PAVC as either Built-in-Audio-Analog-Stereo (BAAS) or Monitor of BAAS (MBAAS). But LMS streams do not appear here, so its input must bypass PAVC?

A good installation will have a new FileType WaveInput under Settings/Advanced/File Types. The WaveInput FileType should have at least the WAV and Flac entries enabled
This is indeed what I see from installing the plugin from the specified repo:

[color=red] For SC 7.3 and later
I have LMS:
Logitech Media Server Version: 7.9.0 - 1446929859 @ Sun Nov 8 04:00:52 UTC 2015
using a SlimDevices Squeezebox v.3.

How to use
There is no user interface. The ALSA stream is played through the URL wavin:<PCM_STREAM> where <PCM_STREAM> is the ALSA PCM name. Typically this will be "default" (i.e. wavin:default )
I have used wavin:0 and wavin:default. Neither responds. (For future Lessons Learned: there is a propensity to use wavein (note the e)... :-(

I also tried wavin:audacity without success.

Quote:

The user should create an entry in Favorites or My Radio Stations, the name is arbitrary and the URL will be typically wavin:default.
That is what I have done, with both wavin:0, wavin:default, and wavin:audacity. And of course restarted squeezeboxserver after each change.

Setup Hints...
TLDR,we can fine tune after we get the basic stream working...

Thanks again for all your work and service.

Kind regards, Andy
