Hi Danni,<br>
<br>
Another approach is to force the ALSA (or actually the kernel) to
assign persistent indexes to your cards. This is done through
modprobe options. See the post <a
href="http://artisan.karma-lab.net/predeterminer-indexes-peripheriques-alsa">here</a>
(in French). <br>
Basically, you edit (and/or create)
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
/etc/modprobe.d/alsa-base.conf to look like this:<span style="color:
rgb(46, 139, 87); font-family: Monaco,'Andale Mono','Courier
New',Courier,mono; font-size: 12px; font-style: normal;
font-variant: normal; font-weight: normal; letter-spacing: normal;
line-height: 15px; orphans: 2; text-indent: 0px; text-transform:
none; white-space: normal; widows: 2; word-spacing: 0px;
background-color: rgb(255, 255, 255); display: inline ! important;
float: none;"><br>
<br>
</span>
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
<blockquote>options snd-usb-audio index=0 # this ensures that your
usb card comes in first<br>
options snd-hda-intel index=1 # if you have an intel card...<br>
</blockquote>
<br>
You can list all the modules which are used by sound devices on your
computer by running "
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
sudo lsmod | grep snd" this into a terminal. You can set the index
number for all of them, and then Jack should find them always in the
same place. This works even for software were you only have a
dropdown list with card index numbers (where method in <a
moz-do-not-send="true" href="http://jackaudio.org/device_naming"
target="_blank">http://jackaudio.org/device_naming</a> does not
work). <br>
<br>
If you have several usb cards, they will all use snd-usb-audio, but
you can still preset their indexes by specifying vendor/product
numbers... This is explained in detail in the post mentioned above.
Please tell me if you need an English translation.<br>
<br>
After editing /etc/modprobe.d/alsa-base.conf, make sure you either
rmmod then modprobe the corresponding modules, or reboot. <br>
<br>
Good luck,<br>
Victor<br>
