[Line6linux-devel] Sample rate in GuitarPort XT

[П. Е. <pup...@ng...>]

Hello! My name is Eugeny, I'm from Novosibirsk, Siberia,
Russia. I'm a user of Line 6 GuitarPort in Ubuntu Studio
11.10. It comes with line6usb module (0.9.1 beta).
Generally, it works fine, thank you for your work! With
It, I can easily play my guitar connected to guitarix via
Jack, and record some demo songs=)
But couple of days ago I decided to make some recordings
with better quality. So, I've just configured 48000 sample
rate instead of 44100 in qJackctl, wanted to setup 24bit
quality, but it doesn't work. qJackctl's indicator shows
44100 sample rate, and ardour creates a session with the
same value.

I've googled a lot, and found some information.
1) In a driver manual I've found that native sample rate
of line6 devices is 39062,5 , and all conversions should
be done by either ALSA, or some software. But writing
plughw instead of hw made JACK not to start.
2) Here
https://sourceforge.net/projects/line6linux/forums/forum/713264/topic/2273283
I've found that GuitarPort only supports 44100 and 16bit
sample rate. This topic is three years old, may be
situation has changed, I don't know...
3) But in official GearBox recording manual I've found
that "TonePort and GuitarPort natively support 44100 and
48000 Hz sample rates. They will
also support 88200 and 96000 Hz, but will perform a sample
rate conversion process to do so." I understand that this
manual is only for Mac and Windows users, but it gives me
a hope...

My question is
Do the words in point 3 mean, that there is a hardware
support for 48000 Hz in GuitarPort? And if answer is
"yes", do you plan to make your driver work with GP on
this sample rate, or may be newer versions of driver
already support 48 MHz?

In any case, thank you very much! Your driver became a
last drop for me to finally migrate to linux from windows
in all my music and home needs! =)
