Help to setup RT-N66U as airplay receiver

[frriction]

Hi,

I want to use my RT-N66U as airplay receiver so I search on google and found this TUTORIAL. I tried to follow the steps on my router, up to the point where sound modules need to inserted into kernel works fine but after that no sound, dbus may start some times and other times it does not start at all , avahi 99% of time does not start. As I am not able to debug my self as I am total noob.

If someone like to help please make working TUTORIAL for Asus router.

I am using MERLIN firmware with Entware installed.

Sound modules are not available for this firmware, and I have no plan to add them either - would be a waste of flash space IMHO, we only have about 4-7 MB free out of 32 MB depending on model.

I understand from the specs that the ac66 comes with 128 mb flash? What is the other 96 mb doing? Thanks

Right now, nothing Asus only partitioned the first 32 MB, the rest is available for a second copy of the firmware (something I've seen them implement over time, but they haven't enabled it in any product yet), and for JFFS (Asus allocates all 96 MB to JFFS, while I only allocate 32 MB to speed up the formating process).

I doubt the partition can safely be enlarged without the CFE being designed to support it, so I wouldn't expect this to happen with the existing products.

How about insert the modules externally using insmod ?

Sure, if you compile the modules. As long it doesn't require any new built-in option in the kernel.

Hi,

I tried with the modules from tomato (same kernel version, extras mips2). Some of them loaded fine, but snd_page_alloc fails. I suspect this is due to an incompatible kernel memory configuration (sparse mem).

I will try to build the modules myself now.

Best regards,
Felix

I have tried this modules. http://tomato.groov.pl/download/K26/build5x-115-EN/extras-mips2.tar.gz

It got inserted perfectly.

I have tried inserting K26RT-N and K26RT-AC which did not worked.

I have tried inserting modules in 108-EN folder from K26 folder in the past and it got inserted and I had a sound output as well.

Hi,

the regular configuration already builds the sound modules, so there is no need to change anything.

The current entware shairport didn't work for me (segfault), so I rebuilt the package using more recent sources. Everything is working with ao output. I haven't been able to get alsa output working, but maybe it's just a missing symlink in dev. Will clarify this in the entware forums.

The only thing Merlin specific is finding the right places for postload scripts etc., but that is the next step

Did you test sound output with alsamixer and madplay ?

Best Regards,
Felix

I had tried it with madplay few month back, i will try again once I get my internet connected.

Did you complied modules or used from the link I posted?

I used the Merlin source and compiled the modules, i.e. follow the Readme and type in "make". Perhaps there is a faster way for compiling kernel + modules only, but it worked out of the box. Modules will be in your kernel build directory (sound/*.ko).

Next steps: install mpd, connect better USB DAC/sound card

segment fault in shairport

Ok I got sound modules and gets inserted with insmod.
here is link of sound modules https://dl.dropboxusercontent.com/u/1396891/Sound modules.zip

I fired up below command to check sound output

wget -O - http://ca.ah.fm:9000 | madplay -

I have working sound output.

I have added following line in avahi config file

enable-dbus=no

so no requirement of dbus.

than blow command

echo "nogroup:x:5:" >> /etc/group

after that I started avahi with this

/opt/etc/init.d/S42avahi-daemon start

and checked is running or not

/opt/etc/init.d/S42avahi-daemon check

But when I tried to run shairport I got segment fault as felix had a problem.

Felix can you share your shairport ipk file please.
