[App_rpt-users] URI frustration

Hi Jay,
The reason I replied is I have been trying ( and I think got a working
solution) to fix a similar problem for weeks, talk about CM108 URI
Frustration.....!

What happened is this...

1. Our VK2CRZ allstar node 2393 has been working for a few years now
but the  PC is a bit old... So we bought a new Intel H55 chipset based
i3 mobo a few months ago to replace it (Model no is ASUS P7H55D-M Pro
mobo).
2. We loaded new ACID install, copied the existing /etc/asterisk
files, unplugged the USB cable existing URI connected to the repeater
and connected to the new Allstar PC....
3. We found the COR and PTT worked fine but the audio was just hum.. :-(
4. Plugged the URI back into the existing repeater and it works fine!!!
5. Looks like an audio path problem.... but the URI green LED was
flashing slower and after a few cold boots we noticed the new boot now
had the URI green LED flashing faster and now the repeater audio
worked fine!!! Did a warm reboot  , URI green was flashing slower and
repeater audio was now hum again....No matter what I did could I get
the URI green LED flashing faster again on the ACID install....

My research indicated that there is some sort of conflict between the
URI sound driver (snd-usb-audio) and the snd-hda-intel driver that is
used for the Realtek ALC886 sound card on this H55 express chipset
motherboard...And maybe a probelm with the H55 USB bus...

This is what I tried...

1. Disable the Sound card in the Bios... It seems that as soon as the
snd-hda-intel drivers are loaded, your URI sound drivers are stuffed
and now unreliable, so that was no fix.
2. Gave up on Centos/ACID and setup up latest Debian 6.x on the ASUS
mobo . Downloaded allstar source code, and setup dev enviroment.
3. Compiled Zaptel first... Compiled OK but zaptel udev was broken on
reboot. Easliy fixed by changing zaptel.rules "=" lines to"=="!!!
4. Compiled asterisk OK and did make install, All OK.
5. Tried loading Realtek ALC886/snd-hda-intel  sound card drivers..
Worked fine but they TOTALLY removed snd-usb-audio URI sound
drivers!!!!
6. Noticed that Realtek ALC886/snd-hda-intel  sound card drivers is
really a ALSA driver install with configure options. Googled and found
options to reload snd-usb-audio drivers.... e.g download from
alsa-projects.org; alsa-driver-1.0.25  and ./configure
--enable-dynamic-minors
7. Disable sound card in bios and reboot. URI drivers are now working again...
8. Now load alsa-oss-1.0.25 drivers or the chan_usradio driver
complains about missing devices...and cold reboot.

Now allstar seems to work ok on the URI card... Warm reboots don't
work all the time however in resetting URI card. Only cold reboot will
reset the URI, in that a warm reboot may end up with the URI green
leds flashing slowly but a cold reboot 9/10 times now seems to set the
URI green leds flashing at the normal rate...
Sometimes a "alsa force-reload" will help reset the URI
I hope this is not a general problem but is one that is mobo/URI specific....

Hope it helps

Anthony, VK2ACP

Yes, my LED appears to be flashing at the right rate. I just have an
audio path problem.. I have the COR and PTT right..

Hi Jay,
I had a similar problem recently. on a repeater that worked perfectly
using an older motherboard...
... To check if its the same problem, is the URI green LED flashing at
its normal rate, e.g. 3-4 times a second  or is it a lot slower?
And are you using the current ACID install????
