M-audio Fast Track Pro not working on HP Probook 4720s

Hi,

I came to this forum because of the advice of Joe Giampaoli, who tried to help me with setting up FTP on my laptop, but he doesn't have any more ideas in the moment what to do with it. I am a bit desperate, thinking of selling that shitty laptop or the M-audio device.

I run it on AV Linux 6, which has all the settings for FTP prepared even on the LiveDVD. I also tried to run it on LiveDVD on different laptop than my HP ProBook 4720s and it was working immediately.
Joe is suggesting that it shoud be some IRQ sharing or settings missing. From what we have tried:

1. Qjackctl settings: Driver: Alsa; Realtime: checked; periods: 256, rate: 44100, periods/buffer: 3, Timeout 500, input device hw:5,1 ; output device 5,0.
2. Playing with the priorities:

According to my ps -eLo rtprio,cls,pid,pri,nice,cmd | grep "FF" | sort -r

99 FF 7 139 - [migration/1]
99 FF 6 139 - [migration/0]
99 FF 14 139 - [migration/3]
99 FF 11 139 - [migration/2]
90 FF 558 130 - [irq/8-rtc0]
85 FF 765 125 - [irq/16-ehci_hcd]
84 FF 1072 124 - [irq/16-mei]
80 FF 1108 120 - [irq/48-hda_inte]
80 FF 1078 120 - [irq/47-hda_inte]
75 FF 546 115 - [irq/1-i8042]
74 FF 545 114 - [irq/12-i8042]
50 FF 780 90 - [irq/46-ahci]
50 FF 774 90 - [irq/20-ehci_hcd]
50 FF 2608 90 - [irq/45-eth0]
50 FF 2592 90 - [irq/19-0000:44:]
50 FF 104 90 - [irq/9-acpi]
5 FF 9512 45 - qjackctl
20 FF 9520 60 - /usr/bin/jackd -dalsa -r44100 -p256 -n3 -Xseq -D -Chw:5,1 -Phw:5,0
10 FF 9520 50 - /usr/bin/jackd -dalsa -r44100 -p256 -n3 -Xseq -D -Chw:5,1 -Phw:5,0
1 FF 9520 41 - /usr/bin/jackd -dalsa -r44100 -p256 -n3 -Xseq -D -Chw:5,1 -Phw:5,0
- TS 9533 19 0 grep FF

we set up the priority of jackd on 84, so then the lines of jackd just above were put a bit differently. But it was sharing the same IRQ (16) with "mei", so we blacklisted mei.
The cat /proc/interrupts looked like this, before blacklisting mei:

CPU0 CPU1 CPU2 CPU3
0: 123 3 0 0 IO-APIC-edge timer
1: 111 119 122 115 IO-APIC-edge i8042

After blacklisting, mei on IRQ 16 was gone.
I also followed joe's blog article suggestions, so my rtirq file looks like this:

RTIRQ_NAME_LIST="rtc usb1 snd i8042"
RTIRQ_PRIO_HIGH=90
RTIRQ_PRIO_DECR=5
RTIRQ_RESET_ALL=0
RTIRQ_NON_THREADED="rtc usb1 snd"

and fast-track-pro.conf file:

options snd_usb_audio vid=0x763 pid=0x2012 device_setup=0x9 index=5 enable=1

I add some other information:
Jackd --version:
jackd version 0.121.3 tmpdir /dev/shm protocol 24

uname -r:
3.0.36-avl-9

lsusb:
Bus 002 Device 009: ID 0763:2012 Midiman M-Audio Fast Track Pro
Bus 002 Device 003: ID 148f:1000 Ralink Technology, Corp.
Bus 002 Device 002: ID 8087:0020 Intel Corp. Integrated Rate Matching Hub

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

I also tried to write
modprobe -r snd_usb_audio
modprobe snd_usb_audio

or to disable networking, but without any success.
The behaviour of Jack is that is starts succesfully ,but when I try to play anything on laptop, it makes short weird sound (reminding the sound how it should be) and than loads of xruns following, unless the Jack is crashing.

We are out of ideas, any other ideas somebody? For looking in the details of our tryouts, those are the links:

Re: M-audio Fast Track Pro not working on HP Probook 4720s

Hi, thanks for this, but I think this might not be the issue, because my version of kernel (not sure it I found it correctly) is 3.0.36, according to linux-image-3.0.36-avl-9 package (and a few others) I found in a package manager...
Am I right?
