what is the purpose of specifiying channel map when usung paplay or parec ? since pacat does provide any upmix or downmix function http://cgit.freedesktop.org/pulseaudio/pulseaudio/commit/src/utils/pacat.c?id=c3cc14153a2f519b2333400bfa942f70bca58c95 the only way seem to be used for handle center and lfe swap or left /right swap do some option such as rate , channel, format only valid for parec ? as paplay obtain these parameters from the file or do paplay or parec support pipe similar to aplay | arecord arecord | aplay paplay can play also raw files, so that's one case where explicit format information is useful. I don't remember if "parec | paplay" is supported (the proper command would be "parec | pacat"). " --rate=SAMPLERATE The sample rate in Hz (defaults to 44100)\n"
" --format=SAMPLEFORMAT The sample type, one of s16le, s16be, u8, float32le,\n"
" float32be, ulaw, alaw, s32le, s32be, s24le, s24be,\n"
" s24-32le, s24-32be (defaults to s16ne)\n"
" --channels=CHANNELS The number of channels, 1 for mono, 2 for stereo\n"
" (defaults to 2)\n"
" --channel-map=CHANNELMAP Channel map to use instead of the default\n"
" --fix-format Take the sample format from the sink/source the stream is\n"
" being connected to.\n"
" --fix-rate Take the sampling rate from the sink/source the stream is\n"
" being connected to.\n"
" --fix-channels Take the number of channels and the channel map\n"
" from the sink/source the stream is being connected to.\n"
" --no-remix Don't upmix or downmix channels.\n"
" --no-remap Map channels by index instead of name.\n"
" --raw Record/play raw PCM data.\n"
do you mean some options are mutally exclusive ?
Yes, some are mutually exclusive. It doesn't make sense to specify both --rate and --fix-rate, since both control the same variable. -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.
