Then you can try to lower the "-p1024" value, by QjackCtl > Settings >
Frames/Periode. I recommend to use sample rate 48000 instead of -r44100,
also available by the settings.

That's bad :(. We can get the snd_emu1 at a better position in this
list, but the shared irq with the graphics is bad.

Show the output of

grep RTIRQ_NAME_LIST /etc/default/rtirq

Make it

RTIRQ_NAME_LIST="rtc snd_emu1

followed by the rest that is already between the " ".

Can you use another slot for the EMU sound card?

It tries to handle unknown machines, most, if not everything is
irrelevant, but you can keep it, just add what I recommended at the
bottom of the list, the echo command does this automatically.
