Audio dropouts seem to be happening more often on my node. I was monitoring an IRLP QSO today while watching console output. Most severe dropouts occurred during the WARNINGS shown below. The DTMF chars appear to be falsing - no tones were sent. Suggestions on troubleshooting appreciated. -- Hungup 'Zap/pseudo-271255635' -- Hungup 'Zap/pseudo-102441634' -- Hungup 'Zap/pseudo-1965758556' [Dec 13 13:18:10] WARNING[9819]: channel.c:2590 ast_prod: Prodding channel 'Zap/pseudo-1412454098' failed -- Hungup 'Zap/pseudo-1412454098' [Dec 13 13:18:10] WARNING[9823]: file.c:602 ast_openstream_full: File none does not exist in any format [Dec 13 13:18:10] WARNING[9823]: file.c:912 ast_streamfile: Unable to open none (format 0x44 (ulaw|slin)): No such file or directory [Dec 13 13:18:10] WARNING[9823]: app_rpt.c:6348 sayfile: ast_streamfile none failed on Zap/pseudo-972989682 -- Hungup 'Zap/pseudo-972989682' -- Hungup 'Zap/pseudo-1265443263' -- Hungup 'Zap/pseudo-745980955' [Dec 13 13:18:27] NOTICE[2485]: chan_usbradio.c:2413 usbradio_read: Got DTMF char 1 [Dec 13 13:18:27] NOTICE[2485]: chan_usbradio.c:2413 usbradio_read: Got DTMF char 2 [Dec 13 13:18:34] NOTICE[2485]: chan_usbradio.c:2413 usbradio_read: Got DTMF char 1 -- Hungup 'Zap/pseudo-1140470725' -- Hungup 'Zap/pseudo-1190238186' [Dec 13 13:19:38] WARNING[2485]: chan_usbradio.c:2117 usbradio_read: Possibly stuck USB read channel.
