What do you think? HW acc. or compile with succesful boot?

dmesg keeps giving me message like:

Code:
[ 1032.363869] HEADSET: No headset plug-in
[ 1032.363882] Headset disconnected, enable internal Mic(DMIC)
syslog has similar entries
Code:
Apr 26 16:31:45 jr-tf101 kernel: [ 1032.653947] HEADSET: No headset plug-in
Apr 26 16:31:45 jr-tf101 kernel: [ 1032.653962] Headset disconnected, enable internal Mic(DMIC)
Interestingly the internal mic DOES work, and I can record my voice with Sound Recorder. Only the playback doesn't work. Have tried all the sound settings in gnome-control-center. It picks up the tegra device but when I try to test the speakers, nothing.

Any pointers? I'd really like to get this working, means I could use my TF as a replacement laptop when travelling....

BTW this is the kernel without HW acceleration.

I assume you're using the kernel from lilstevie's git.
Have you tried running alsamixer? IIRC, something was disabled by default in it - we discussed it earlier in that thread.

Admittedly, I used KDE and never tested it under Gnome, but that shouldn't be relevant. (Don't know which DE Braernoch used.)

I'm using my own image - armhf, there will not probably work HW acceleration?

I tested sound, wifi, touchapad + keyboard, touchscreen, battery status in tray and everything works.

Flashable package for CWM - SBKv2 - mount loop from internal memory > /sdcard/ubuntu.img

The zip posted in the previous post only had the kernel blob.

I think all you have to do is copy 3.1 kernel blob to a previous kernel zip file that contains all the files. You need the bootimg and initrd files.

No. Only replace kernelblob in the zip package for flash or flash with dd.

Here is complete package for flash in CWM > http://forum.xda-developers.com/show...4#post25575064

Hey jozka
Can you post a zip of your initrd separately, i.e. not compiled into the kernel? I would like to change the mount point for the /dev/mmcblk-p7 partition. I find that when I mount it to /media it interferes with the mounting of other devices to the /media directory by the hal daemon (e.g. new SD card or USB stick plugged in).

(I'm running successfully on a SBKv2 device with loopmounted rootfs and the loop is setup in the initrd, but that is on a 2.6.36 kernel w/o HW accel. I'd like to try the same setup with the new 3.1.10 kernel. Or can you use the same initrd as for 2.6.36 kernel?)

Remind me, the modules folder - what do I do with it ? Uncompress it to lib dir?

Do "uname -r" in a terminal to get your kernel version.

Uncompress to /lib/modules/xxxxxx
where xxxxxx is the output from the previous command.

I thought on nvidia website are drivers only for armel.

I made image with debootstrap --arch armhf.

SBKv2:
you must copy the lib - 3.1.10 folder to /lib/modules/
