             Summary: streaming MP3 in wideband leads to screaming noise
                 Key: ASTERISK-26086
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-26086
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Resources/res_musiconhold
    Affects Versions: 13.9.1
         Environment: Debian Linux 7.11
            Reporter: Jens Bürger


On a freshly compiled Asterisk 13.9.1 with example configuration, streaming MoH in wideband (16 kHz) only leads to an screaming noise.
When playing in 8 kHz, streaming works fine::
Excerpt from musiconhold.conf:
[streamtest]
mode=custom
application=/usr/bin/mpg123 -q -r 8000 --mono -s http://mp3.theradio.cc

When streaming in wideband like this:
[streamtest]
mode=custom
format=g722
application=/usr/bin/mpg123 -q -r 16000 --mono -s http://mp3.theradio.cc

The client hears only a screaming noise.

This was verified with two different clients (Snom 370 hardware phone, Jitsi soft phone)
