Problem:
- After installing Linux on a Sony VAIO VPCEC1M1E, the sound card is recognized correctly but the sound does not work.
Solution:
- This is a known bug. For more details, see [1].
- To solve this issue, you have to modify a sound card key using hda-analyzer [2].
- Get the basic run.py script:
wget -O run.py http://www.alsa-project.org/hda-analyzer.py
- Execute it:
python run.py
- Go to Node[0x19] PIN (left hand side pane) -> Widget Control (right hand side pane) -> change the value of VREF to HIZ.
Note:
- The following instructions describe how to set the sound card key automatically at each reboot of the system.
- Download the following file and extract it:
ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/misc/hda-verb/hda-verb-0.3.tar.gz
- Go to the directory and compile the program using make:
make
- Copy the compiled program to /usr/bin:
cp hda-verb /usr/bin
- Open the file /etc/rc.local:
vi /etc/rc.local
- And insert the following line:
/usr/bin/hda-verb /dev/snd/hwC0D0 0x19 SET_PIN_WIDGET_CONTROL 0x22
- Save the file and reboot the system.
