[SOLVED] Lost Tuba CineBass booster
Hi all. I have Acer Aspire 5739g and after upgrade kernel to version 3.3.1 sound lost low frequencies. I watched this topic and hoped, that after bump to 3.3.3 this problem will disappear, but nothing has change. On linux-lts all works fine.
my modprobe.conf contains the following lines:
options snd-hda-intel model=acer-aspire-6530g
options snd-hda-intel enable_msi=1Maybe someone has the same model without this problem? I also thought to send a bug report to developers, but i don't know how and to whom 
P.S. Sorry for my English, it is not very good.

Re: [SOLVED] Lost Tuba CineBass booster
After viewing the source code linux-lts, to solve this problem, I wrote a patches, they work for my Acer Aspire 5739g with
options snd-hda-intel model=acer-aspire-6530g
options snd-hda-intel enable_msi=1 in modprobe.conf and must work for Acer Aspire 6530g

Re: [SOLVED] Lost Tuba CineBass booster
Hmm...I found that with my patch, if I connect the headphones, the sound keeps going from speakers too. This problem should be described in another topic, so the message is left as a warning!
