Hi,
Back to an unresolved issue I posted sometime ago. I did some more tests this
week and found out the following (I did this test twice and obtained the same
results in two different machines):
1) I install Ubuntu Studio 12.04 from scratch;
2) I try it with my PreSonus AudioBox 1818VSL USB interface. Open Jack, Jack
sees interface, Start Jack, Start Hydrogen, Play a Demo, it all works and I get
sound out. Happy!
3) I then turn off the computer and the interface. Then turn them back on;
4) I repeat the steps of #2: open jack, jack sees interface OK, I start jack, I
start Hydrogen, open a Demo, and... no more sound comes out of the interface. I
don't even see the meter lights anymore. Still, Jack recognizes it and starts
correctly. But no sound anymore.
With this, I rephrase my original question. The problem was not a recent
software update, as I had thought: now even with a clean, fresh install of
Ubuntu Studio, the interface works the first time, and after rebooting the
computer, it never works again.
I've tested the audio interface on a Mac computer and it is working (in fact I
bought this PreSonus recently, it's brand new). If I boot Ubuntu studio from a
live CD, the interface works again.
Any ideas on how to solve this mystery?
Thank you very much for any help,
Bruno

Hi,
I didn't use synaptic, but I copy below the contents of history.log from
/var/log/apt/
The interface was working fine until 2012-09-24. After those updates it stopped
working.
Thanks for any help,
Bruno

3. USB interface stopped working after update

5. Re: USB interface stopped working after update (Ralf Mardorf)
------------------------------------------
Hi,
I have Ubuntu studio 12.04 installed on one laptop, and regular Ubuntu on
another (also 12.04). Until a few days ago, both systems used to work fine with
a PreSonus AudioBox 1818VSL USB interface. All of a sudden, the two laptops are
no longer working with this interface. My only guess is that this was caused by
some kind of software update (I usually do all required & recommended updates
suggested by Ubuntu).
To be more precise, Jack still sees the USB interface as before; I am able
to start jack with the PreSonus, I see all the ins and outs in the connection
window. But no sound seems to arrive in the hardware. No sound comes out. I
used to see the AudioBox meters lighting up last week; they no longer light up
this week. I've tested the audio interface on a Mac computer and it is working.
In fact, if I boot Ubuntu studio from a live CD (that is, without any recent
updates), the interface works again.
Has anything like this happened to other people this week? Any tips on how
to solve the problem?
Thank you very much,
Bruno

If you upgraded using Synaptic, there'll be a history about the upgraded
packages. Please send a copy of this list.
