  OK that's the first significant information !

  OK I ignored this bypass.

  Clear it works. Only have now to tell to ecasound to do the
  same because output description is not exactly the same as in
  aplay or player but now I precisely know waht have to be
  done.

[Alsa-user] volume problem

2015-09-29 Thread Bruno Schneider 
I have a notebook, where speakers suddenly stopped working. I use
Debian testing (Stretch). Although speakers don't work, headphones
work fine.

It is not a hardware problem because they work If I boot into some
other distro I have.

Debian uses PulseAudio, but if I disable PulseAudio, the problem
persists. So I guess the problem is in ALSA underneath, and it must be
something muted or sound not routed properly.

I'm testing with aplay, like this:
   $ pasuspender -- aplay -D hw:1 file.wav

No errors given. Just no sound through speakers. I can hear the sound
if I plug headphones.

Looking at mixers (amixer and alsamixer), I can't find anything muted.
I have attached amixer output as a text file.

Can anyone help me debug this?

According to the documentation, something like

  ecasound -i somefile.mp3 -o alsa,default:STX
