Problems with snd_es18xx

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


There is a problem, when trying to use Guillemot Maxi Sound Home 64 Studio
- I mean: I can operate all the controls offered by ALSA, I can even record
the sound (tried to record something from microphone) - but I can't hear
anything at all, like there were no cables connected to speakers.

The card itself is, of course, fully operational (checked it from within
FreeDOS), it has ES1868F chip on the board.

Some more info:

(Pay attention: no ESS1868 nor anything like this)

It's ALSA package bundled with kernel. From the application's side
(like mp3blaster, record, bmp or the like) all seems to be fully operational,
I can use alsamixer or aumixer to change the settings - but the speakers
are still silent. And one more detail: the card cannot be detected by
alsaconf (ALSA-utils 1.0.14).

What can be the problem?
