Hi everybody,
I am not able to configure Hydrogen to run with jack and the ffado drivers. I am using ubuntu 8.10. To run hydrogen with freebob I had to modify this part of hydrogen.conf:

#
# alsa_pcm:playback_1
# alsa_pcm:playback_2
# #NO_JACK_TRANSPORT
# true
# false
#

in this:

#
# freebob_pcm:P0_dev1p_LineOut 1+2 left
# freebob_pcm:P1_dev1p_LineOut 1+2 right
# #USE_JACK_TRANSPORT
# true
# false
#

using the names of the client anf the ports that I found with the command

# jackd -v -d freebob

But the same operation with the ffado drivers doesn't work!

Can anybody help me?

Hello!

I use FFADO & Hydrogen, and I must say it has worked "out-of-the-box".
However before I was using FreeBoB. After switching to FFADO, I did not change anything in my Hydrogen config (if I remember correctly).
But I had changed one thing in the very beginning - my jack ports are named like 'system_X', and do not have such specific names like you have set up in your config.

If you want I can post my config in here when I return home.

Cheers!

hi nicola

normally if you use hydrogen together with jack it is not important what happens in a lower audio layer(ffado). so the easiest way to configure hydrogen is over the hydrogen preferences dialog. in tab audio system you can choose jack. if you press ok normaly h2 will use the jack driver. the default connection is Hydrogen>out_L + out_R to system>playback_1 + playback_2.

imo, remove or move your old modified h2 config file and restart h2 AFTER you have start jackd. and if you start jackd e.g with qjackctl you can use the qjackctl connection dialog to make your connections- or to see the connection. after h2 is up open the pref dialog in h2 and choose jack and press ok. normally this is all. no manually config is necessary.

and important, start h2 after starting the jack driver.then hydrogen will connect over the jack driver by default. because "auto" is the default pref. setting in h2. but it it is better to use jack in pref dialog. the jack transport buttons in hydrogen will only displayed if you have choose the jack driver. this is a small bug in h2.

Try system:playback_1 and system:playback_2 in your hydrogen.conf, that's what I use.

a) Calculate the magnitude of the maximum orbital angular momentum for an electron in a hydrogen atom for states with a principal quantum number of 6.

b) Calculate the magnitude of the maximum orbital angular momentum for an electron in a hydrogen atom for states with a principal quantum number of 34.

c) Calculate the magnitude of the maximum orbital angular momentum for an electron in a hydrogen atom for states with a principal quantum number of 206.
