Bug#891709: rtaudio library writes debug info to stderr

[John Belmonte]

Package: rtaudio
Severity: important

Dear Maintainer,

Please remove --enable-debug compilation from the rtaudio build.
It causes debug info to be written to stderr, such as ALSA
device details:

  RtApiAlsa: dump hardware params just after device open:

  ACCESS:  MMAP_INTERLEAVED RW_INTERLEAVED
  FORMAT:  S16_LE S24_LE
  SUBFORMAT:  STD
  SAMPLE_BITS: [16 32]
  FRAME_BITS: [16 96]
  ...

Clients using the rtaudio library should have control over
what's emitted on stdio.  If the info is important for some use
cases, please ask upstream to put the logging under runtime
control.

Regards,
--John
