issue with TI FW card

Post by zby »

Hi.

I decided to turn my vacant Fujitsu Siemens E751 laptop into a light recording platform, but jackd dies or freezes.
Facts:
-- A new Startech EC13942 FW Expresscard/34 with TI XIO2200A chip
-- An Edirol FA-101 (Roland recommends TI based FW chips as well as ffado guys)
-- CentOS 7 64bit
-- 4.18.7 PREEMPT custom-built
-- jack-audio-connection-kit-1.9.9.5-6.el7.x86_64
-- libffado-2.1.0-4.el7.x86_64 , libffado-2.4.1 (custom-built for testing purposes)
-- audacity-2.1.1-1.el7.x86_64

Distros tested with the HW (installed or live media):
-- CentOS 64bit: Failed
-- ArchLinux audio live: failed
-- KXStudio: failed
-- 64studio: failed
-- CentOS 6 (32/64bit), KVM guest): failed

Windows not tested at all.

Further info:
The ffado-test utility discovers my FW audio interface without problems and the ffado-mixer starts up fine as well. So does the ffado-dbu-server. However, jackd dies no matter what version of ffado I use currently (2.1.0 or 2.4.1). lspci lists the XIO2200A chip and its PCI->PCIe bridge.
When I start jackd (eg. jackd -R -P70 -d firewire -r48000) it looks like the connection to the FA-101 gets established, but later jackd dies or freezes for a lot of dropped packets.

I have two other laptops to test the FA-101 and it works fine on the oldest one (Fujitsu Siemens 8020e, CentOS 6 32bit, TI TSB43AB21 on-board chip, 6-4 cable) and works with cracks on HP 2540p (CentOS 7 64bit, Ricoh R5C832 on-board chip, 6-4 cable). Thus, the FA-101 is OK.


I fear that the above mentioned Startech EC13942 is simply either not suitable for use with my laptop or not suitable for use with FW audio at all.
My question is whether you guys encountered similar problems. Better to say, what PCIe/34 card you use or works for you fine.


Thank you
