System: NetBSD
Architecture: i386
Machine: i386
>Description:

The pad_output test case of the dev/audio/t_pad test program is now
failing on the i386 testbed, and also on real amd64 hardware:

  http://releng.netbsd.org/b5reports/i386/2019/2019.05.09.07.38.44/test.html#dev_audio_t_pad_pad_output
  http://www.gson.org/netbsd/bugs/build/amd64-baremetal/2019/2019.05.09.13.07.35/test.html#dev_audio_t_pad_pad_output

This did not result in an automated report by the i386 testbed because
the test case had not been consistently passing before it started
consistently failing:

 Module Name:	src
 Committed By:	isaki
 Date:		Thu Jun 20 12:14:46 UTC 2019

 Modified Files:
 	src/distrib/sets/lists/tests: mi
 	src/tests/dev/audio: Makefile h_pad.c t_pad.sh
 Removed Files:
 	src/tests/dev/audio: t_pad_output.bz2.uue

 Log Message:
 Rewrite t_pad test.
 Previous version compared the pad's output binary passed mulaw-slinear
 conversion and frequency conversion with the prepared "good result".
 In such case, a test may fail when the implemantation changes.  In fact,
 the frequency conversion algorithm was changed in isaki-audio2, so
 output waveforms is not completely the same (but that's no problem with
 the audio waveforms).
 New version uses slinear_le/2ch/44100Hz input data and compares the
 output binary with the input data.  pad with no conversions should
 output the same binary.
 Fix PR kern/54187.
