Post 'aplay -v -Dplughw:0' log. I presume, with a mono wav file. Without any .asoundrs or /etc/asound.conf: aplay -v -Dplughw:0 /home/lyakh/c1.wav Playing WAVE '/home/lyakh/c1.wav' : Signed 16 bit Little Endian, Rate 8000 Hz, Mono aplay: set_params:1053: Unable to install hw params: ACCESS: RW_INTERLEAVED FORMAT: S16_LE SUBFORMAT: STD SAMPLE_BITS: 16 FRAME_BITS: 16 CHANNELS: 1 RATE: 8000 PERIOD_TIME: 125000 PERIOD_SIZE: 1000 PERIOD_BYTES: 2000 PERIODS: 4 BUFFER_TIME: 500000 BUFFER_SIZE: 4000 BUFFER_BYTES: 8000 TICK_TIME: 0 It shouldn't matter, but alsa is installed under /usr/local/... and I'm starting all alsa utilities as LD_LIBRARY_PATH=/usr/local/lib/ aplay... and it works with stereo, but not with mono. But just in case that plug-in magic does something funny with the environment, there could be a problem with that...
