I'm using Wine and ES 4.11. Additionally, I'm using a serial pedal with a USB to serial adapter. I've discovered an "issue" with the USB to serial adapter with some computers running Ubuntu that I'd like to share. I ran into this "issue" on an HP Thinline Tricore AMD-based computer. If your USB to serial adapter with your foot pedal suddenly loses its mind and ceases to work during a playback, the following resolved that issue:
Edit grub and add the following to the end of your boot line: noapic irqpoll pci=routeirq
Save your changes and reboot. That resolved the "issue" with the USB to serial adapter suddenly ceasing to work. Express Scribe performs as designed thereafter with no issue. I was forced to figure that out because the computer had no available PCI ports for a half-height serial card. Hope this information helps others. If you're unfamiliar with how to edit your grub, here's how:
sudo gedit /boot/grub/menu.lst [Enter]
(you will have to enter your password)
add "noapic irqpoll pci=routeirq" (without the quotes) to the end of the line with the word "quiet splash" on it. Save your change. Restart your computer. The former anomaly should no longer present itself.
