My iMac has only two speakers, and I am not using external speakers. When I boot into OS X, the audio is rich, full of bass, and everything I expect. When I boot into Jaunty, I get no bass. Please note: there is no subwoofer in this machine! http://www.everymac.com/systems/apple/imac/stats/imac-core-2-duo-2.4-20-inch-aluminum-specs.html
The line I used to configure alsa-driver, alsa-lib, and alsa-utils is:
sudo ./configure --with-kernel=/usr/src/linux-headers-$(uname -r) --with-cards=hda-intel --with-oss=yes
I downloaded the latest alsa-driver, alsa-lib, and alsa-utils and installed without error. cat /proc/asound/version returns:
Advanced Linux Sound Architecture Driver Version 1.0.20.
Compiled on Aug 10 2009 for kernel 2.6.28-14-generic (SMP).
Furthermore, uname -a

For sudo gedit /etc/modprobe.d/alsabase.conf , I have tried just about every model within the guide at http://ubuntuforums.org/showthread.php?t=611345&highlight=imac+7%2C1
Currently, it is set to:
options snd-hda-intel model=asus-a7m
... and that setting has always been the only line within alsabase.conf
/home/litropy/.asoundrc just has the include for .asoundconf - no custom settings there.
I have tried adjusting various volume sliders. As of the driver update, there is no more clipping (crackling). And once again, after all this, I still have no bass. Please help me out.
