Hi All,
I have sound issues with my laptop, I cannot get 5.1 sound and jack sensing does not work (but works on Windows 7; dual-boot).
I have an Acer Aspire 5930 (chipset: ALC888) running Ubuntu 10.10 (64-bit). I have tested with Alsa 1.0.23 (which comes with Ubuntu 10.10) and also compiled Alsa 1.0.24. Here is the Alsa-info with Alsa 1.0.24 (latest), and "model=auto", http://www.alsa-project.org/db/?f=2cbab ... 31dc6a7d70 http://www.alsa-project.org/db/?f=2cbab995516f4b56a7faecf537f61f31dc6a7d70
Here is alsa-info with "model=acer-aspire-6530g", http://www.alsa-project.org/db/?f=40992 ... 17160cde64 http://www.alsa-project.org/db/?f=409923a3d8f042804e61f21c7b8ae917160cde64
However, on Linux, 1. the sound volume is too low compared to Windows 7. For example, 50% on the volume bar in Ubuntu is roughly equivalent to 10% in Windows 7. 2. the subwoofer control bar in Sound Preferences Settings seems to control the master volume bar. 3. it seems that only 2 speakers actually work (Front Left and Front Right) as tested with speaker-test -c6 -twav 4. when I plug in the headphones jack the internal speakers don't get muted, instead I have combined sound output.
I tried to change the model from auto to "acer" (tested all the acer and the 6stack-dig models and settled down to acer-aspire-6530g as a popular suggestion) but it didn't change much. (You'll find the alsa-info.txt as an attachment to this message.)
Is there any possible solution or suggestion for this problem? I am happy to try out patches.
Thanks, Elisavet
