The TS11 series use Intel Cougar Point. I'm using slackware current with kernel 2.6.38.7 but I presume all distros will have similar problems. If anyone can help solve them I'd be most grateful - especially the sound issue!

1. sound (alsa)

Running aplay -l gives three SPDIF / HDMI devices, the laptop has one HDMI so the snd-hda-codec parameters are not correct. Unfortunately I have been unable to find the model.

2. backlight controls

Do not work at all. I'm investigating.

Hi,

referring to the sound, you can use alsaconf as root, this utility will configure your sound-card. If you don't know which device you should chose when alsaconf asks you, try all of them, if it was wrong execute alsaconf again.

Referring to the backlight. There are special kernelmodules for verious laptops. you should look at the kernel-sources (in /usr/src/linux execute "make xconfig" and navigate to "Device-Drivers"->"x86-platformspecific Drivers") there you can find out if there are any modules for your computer. You can load with modprobe. Read the manpage for modprobe.

The backlight is fixed using "append="acpi_osi=Linux" in lilo/grub. It appears the laptop bios has a few bugs. It works fine after setting this, although it does not get remembered after coming out of standby etc.

The laptop is actually a rebranded Acer 5650g (acer bought packard bell a while back) without the NVIDIA gpu.

I tried alsaconf but it made no difference. Output was...

could you please post the output of and Markus

How interesting it does come up with Acer, I didn't catch it. Sadly device=acer doesn't do anything in modprobe.

As far as I can see, your sound should work, there's nothing missing. Did you try alsamixer on the commandline and check if the buttons are set correctly?

Markus

Yup. What is unusual is it has worked once or twice but I have been unable to duplicate. I thought it was down to a kernel issue so I downgraded a bit, but now that makes no difference.

Cheers, Andrew

Tried everything and googled the earth for a solution. Now filed as an alsa bug.
