Thanks in advance. 2014-03-08 18:16 GMT-03:00 Leo Combes <combesl@xxxxxxxxx>: > Hi, > I have bought a Maya 44 USB, with 4 output and 4 input channels. > > http://www.esi-audio.com/products/maya44usb/ > > The soundcard works fine in playback, but in recording has some > problems, specificly there is no way to control the volume of the > recording on inputs. > It seems to be default setted to 50%. > > Alsamixer, in playback section shows 3 controls, "speaker", "line" and "line1". > But, if I choose capture, it shows "This sound device does not have > any capture controls". > It seems like there are controls, and they work fine, running on Windows. > > I searched the problem on Google and I found a lot of users with the > same problem. > > The most interesting thread that I found, is one on this mailist, > sadly after some messages, user didn't catch up with the conversation: > > http://mailman.alsa-project.org/pipermail/alsa-devel/2011-November/046242.html > > I have a hardware mixer connected to 2 inputs of the Maya.
