The disk system on your computer was not able to keep up with Ardour.
Hey, dear Ardour community.
I'm encountering the following problem when I try to record with Ardour:
"The disk system on your computer was not able to keep up with Ardour."
This happens after a few minutes while recording 8 tracks simultaneously via the Edirol FA-101 Firewire-Interface. (no plugins or effects added)
I'm using UbuntuStudio 9.10 with 2.6.31-9-rt Kernel and Ext-3 filesystem.
My Machine is a Lenovo N200 Notebook with 1.8Ghz Dualcore CPU, 2Gb RAM and 4200RPM SATA Harddrive.
hdparm says the following about the disk:
Timing cached reads: 1588 MB in 2.00 seconds = 794.00 MB/sec
Timing buffered disk reads: 160 MB in 3.02 seconds = 52.90 MB/sec
As I've read in other posts I've found via Google (the search engine in this forum doesn't work), SATA drives don't seem to have the necessity of running in DMA mode. (this was one of the suggestions I've already found)
Additionally, I already added myself to the "audio" group and edited the limits.conf -file (rtprio:99, memlock, nice:-19).
I tried using Freebob and FFADO with no success.
The issue occurs quite randomly. Sometimes after just a few minutes, sometimes after 20 minutes of recording. Once I "faked" the input signal on all 8 tracks (because I didn't have 8 mics to plug into the FW-Interface) by connecting the outputs from the Vlc-player to each of the 8 Inputs via Jack and started recording with Ardour. This test-run went right through, 40 minutes long, until I manually stopped it.
Thank you very much in advance for any suggestions.
