Hello everyone.
I bought a MAYA44 USB+ sound card to use in Linux and although is on the list of compatible devices at http://www.alsa-project.org, I can not make it work properly. Maybe something is missing because the site says "under development", so I write hoping that someone can help me.
MAYA44 USB+ is identical to MAYA44 USB, only adds a aluminum enclosure (http://www.esi-audio.com/products/maya44usb+)
In a quick search, I see that others have the same problem, but could not find a solution. If someone can put me in the right direction, I have no trouble doing the tests we need, recompile kernel modules or anything else.
The problem is that there's no volume control on the input lines, and default volume is too low. In alsamixer, if I select "capture" for this soundcard it shows "This sound device does not have any capture controls". I tried turning up the volume on my sound source, but all I achieve is a saturated, low sound.
In Windows, the soundcard works fine and have input volume controls. Specifically, have 12 volume controls, in pairs:
INPUT 1, 2
INPUT 3, 4
MONITOR 1, 2
MONITOR 3, 4
OUTPUT 1, 2
OUTPUT 3, 4
Each pair, has a mute button.
For comparison, I took a sample of sound from a external hardware mixer and recorded in Audacity with Linux.
Later, on a Windows computer, I installed the original drivers, connect the soundcard and I repeated the process of recording the same sample also in Windows Audacity at same "hardware" volume.
The result is that in Windows I reach a level of 0dB on the Audacity VU meter with clear audio. In Linux, the same sample not exceed -24dB.
This gives me the idea that the Linux driver, as it has no volume control recording, leave the default volume of the soundcard, which is at the minimum. As a note, Audacity in Linux shows me options for record with 1, 2 and 4 input channels in MAYA and I can select it, but the volume input slider is grayed out.
I did a search and try different configurations about .asoundrc, try build a module with quirks or even make a driver from scratch, but for now is out of my reach and all I got are errors or noises in my speakers. I also try installing the last kernel from sources, uninstalling pulseaudio, try on other computers, without luck.
To make the long story short, the only thing missing are the input volume controls.
No errors on syslog or dmesg.
Here I copy the technical information that I have, hopefully someone can help me, If anyone needs any further detail, just ask:
