[asterisk-users] TDM400P FXO click sounds

[ggonzalez at telviso.com.ar]

Hi all and thanks for every suggest about my problem, I found that my TDM400P
was sharing IRQ with onboard sound device using cat /proc/interrupts, lspci -v
and lspci -vb. When I disable all unnecessary hardware on my machine and test
it, clicking sounds continue on the line with the same intensity; again using
lspci -vb i found that:

01:00.0 VGA compatible controller: VIA Technologies, Inc. Unknown device 3230
(rev 11) (prog-if 00 [VGA])
        Subsystem: Micro-Star International Co., Ltd. Unknown device 7253
        Flags: bus master, 66MHz, medium devsel, latency 64, IRQ 11
        Memory at c0000000 (32-bit, prefetchable)
        Memory at dd000000 (32-bit, non-prefetchable)
        Capabilities: [60] Power Management version 2
        Capabilities: [70] AGP version 3.0

04:04.0 Communication controller: Tiger Jet Network Inc. Tiger3XX Modem/ISDN
interface
        Subsystem: Unknown device b119:0003
        Flags: bus master, medium devsel, latency 64, IRQ 11
        I/O ports at be00
        Memory at dfaff000 (32-bit, non-prefetchable)
        Capabilities: [40] Power Management version 2
 
Now TDM card share IRQ 11 with onboard vga controller. I have a sata raid 1
level running on the box too and cat /proc/interrupts show me:

  0:   23572057          0    IO-APIC-edge  timer

LOC:   23572106   23572083
ERR:          0

Disabling ACPI from kernel at boot, the systen cant detect TDM card.
Again, running debian etch x86_64. Click sounds continue again. Running zttest
I get:

--- Results after 55 passes ---
Best: 100.000000 -- Worst: 67.395020 -- Average: 98.757324

I change from one slot to other and the problem continue. What follow to solve
this issue? Thanks for any suggest.
