Hi, sorry I can't quote the original message. I'd forgotten that I'd
unsubscribed from this list, but when I tried resubscribing, the mail
bounced. bigfoot.com only forwards 25 messages per day, and apparently
I've reached my quota.
So anyway, running with -z:nodb produces the following:
****************************************************************************

. . .
(eca-chainsetup-parser) Double-buffering disabled.

(eca-chainsetup) 'rtlowlatency' buffering mode selected.

(eca-engine) Using realtime-scheduling (SCHED_FIFO).
(audioio-alsa) warning! playback underrun - samples lost! Break was at least 20.70 ms long.

- [ Chainsetup disconnected ] ----------------------------------------------
(audioio-alsa) WARNING! While writing to ALSA-pcm device C0D0, there were 1 underruns.
Using -z:db,x still doesn't solve things. I still receive underruns.I
can decrease the number of "xruns" by increasing the db value, but
even 2400000 doesn't eliminate xruns (I'm assuming those are bad? :)
Decreasing to 25000 increases to 104 xruns. Note that I'm still
hearing roughly the same amount of audio.
As far as looping, I used cs-toggle-loop (is that -tl?)
Please let me know if there's anything else I can do to help debug
this.
