Description Andreas Tunek 2011-05-08 16:20:51 UTC
The sound from the speakers is pretty weird, seems like there is no bass at all. Using MacOSX I get a much more normal sound.

Sorry but this doesn't sound like a problem with alsa-firmware.
alsa-firmware contains firmware drivers for a very small number of specialist 
sound cards only.

Please be aware that problems with sound can be caused by many different
software components within a Fedora system (including ALSA kernel modules,
PulseAudio, desktop volume controls, individual applications and more) and
you may find it easier to get some informal help to track down the problem 
before filing bugs (if necessary), so that you can file them against the 
right component and the appropriate person can help.

Help resources are listed here:

If you still believe your problem really is with
alsa-firmware, please re-open this bug with further details. Alternatively, if you identify the software causing the problem, you could change the Component accordingly and re-open it.

Guess it is alsa-lib...

Comment 3 Andreas Tunek 2011-05-10 20:18:04 UTC
Also, can you please open it again?

Also, if you plug in head phones audio from speakers do not stop.

I had a similar issue but found that using alsamixer to turn the volume up on the "front speaker" and un-mute the "surround speaker" fixed things for me.

This is because pinconfigs set by alsa for cirrus chip are wrong, GPIO dir too :
