Thanks David, I will investigate the timer res and get back to you.... regards Anthony, VK2ACP On Sep 21, 2012 2:13 AM, "David McGough" <kb4fxc@inttek.net> wrote:
Hi,
I've seen URI driver issues in the past as well. In my situation, all was working great on an older MoBo. Then, for some new repeaters, I switched to a latest-generation Zotac Mini-ITX board with AMD 3.2GHz dual-core CPU. These boxes exhibitied similar green LED issues and "Mr. roboto" like audio problems. I found the problem was due to a kernel timer/compatibility bug with the new hardware....A was using the default ACID install at that point--CentOS 5.3, 2.6.18.xxx kernel.
I resolved the issue by downloading and "hand cooking" the latest (at that time--2.6.30.5) kernel which had properly working hi-res timer code. I also hacked the zaptel-dummy driver to use the hi-res timer. Since these fixes, both boxes have run perfectly--the latest uptime (which I just checked) is 208 days. Also, neither box exhibits any cold boot / warm boot issues.

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

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????
