Hi Jeff,

please, bear in mind two rules:

1. don't just reply to me, but always use the "reply-to-all" feature in your mail client. This way, all people on the ALSA list can follow the discussion and chime in. 2. don't top-post, always reply using proper quoting.

I'm running Ubuntu Studio 10.04 x64 with realtime kernel from http://ppa.launchpad.net/abogani/ppa/ubuntu lucid (linux-realtime - 2.6.33-29.1); my motherboard is ASUS M4A78T-E onboard VIA sound, Nvidia 460 GTX Video card; AMD 955 X4 CPU. Link to kernel used https://launchpad.net/~abogani/+archive/ppa/+packages?field.name_filter=&...

I searched for instructions on how to do this, with no good results; so I must ask someone that knows how.

Things are a little more complicated as modern Linux distributions use techniques like initramfs.

For Ubuntu, you should follow one of the tutorials. Two I found are here:

https://help.ubuntu.com/community/Kernel/Compile http://parabing.com/2011/04/28/ubuntu-natty-a-custom-kernel-is-what-you-want...

That looks comprehensive. Just don't download the ubuntu Kernel sources as described but clone the ALSA repository (which you already did).

And instead of downloading the patches as described, just use "git apply" on the file I sent you. On case you want to revert the patching and return to the kernel you originally cloned, just call "git reset --hard".

Just to make sure I do this right, since I've never compiled ALSA driver before; these are the instructions I used:

1. git clone

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6.git 2. cp 0001-ALSA-snd-usb-add-quirks-for-Roland-GR-55.patch /sound-2.6 3. cd sound-2.6 4. patch -p1 < ./0001-ALSA-snd-usb-add-quirks-for-Roland-GR-55.patch 5. make x86_64_defconfig 6. make 7. make install

This worked, not tested; I still need to get the kernel to see it; I did this in my home directory; where should I move it?

I see a file called vmlinux, 19.7 MB executable; I take it this is the new ALSA Driver.

I do see vmlinux files that are new in these folders; which would seem to me that they got where they need to go with the make install command. /proc/4055/cwd /proc/4055/cwd/arch/x86/boot/compressed

Now do I need to compile this into the Kernel, if so, what kernel do you recommend; realtime, low latency or normal; and what version?

I would first go for a normal kernel configuration, and once the driver supports the device, care for optimisation.

HTH, Daniel
