Bingo.  Just won't get a physical connection.  Initializes and dials
fine...starts the handshake and never finishes.  Ends up timing out on the
handshake.

I looked at the logs and this was one of the attempts with soundcard:

Jan 25 21:47:48 kamikaze ppp[834]: Phase: Enter pause (3) for redialing.
Jan 25 21:47:51 kamikaze ppp[834]: Phase: Redialing timer expired.
Jan 25 21:47:51 kamikaze ppp[834]: Phase: Connected!
Jan 25 21:47:53 kamikaze ppp[834]: Phase: Phone: 2529670
Jan 25 21:48:43 kamikaze ppp[834]: Warning: DialModem: dial failed.
Jan 25 21:48:43 kamikaze ppp[834]: Phase: Modem: Connect time: 52 secs: 0 octets in, 0 octets out
Jan 25 21:48:43 kamikaze ppp[834]: Phase:  total 0 bytes/sec                    

And here's a successful right after that with no soundcard:

Jan 25 22:04:55 kamikaze ppp[212]: Phase: Using interface: tun0
Jan 25 22:04:55 kamikaze ppp[213]: Phase: PPP Started.
Jan 25 22:05:08 kamikaze ppp[213]: Phase: Connected!
Jan 25 22:05:10 kamikaze ppp[213]: Phase: Phone: 2529670
Jan 25 22:06:01 kamikaze ppp[213]: Phase: NewPhase: Authenticate
Jan 25 22:06:01 kamikaze ppp[213]: Phase:  his = PAP, mine = none
Jan 25 22:06:01 kamikaze ppp[213]: Phase: PAP: ibc
Jan 25 22:06:01 kamikaze ppp[213]: Phase: PapInput: ACK
Jan 25 22:06:01 kamikaze ppp[213]: Phase: Received PAP_ACK (Login Succeeded)
Jan 25 22:06:01 kamikaze ppp[213]: Phase: NewPhase: Network
Jan 25 22:06:01 kamikaze ppp[213]: Link:  myaddr = 208.236.238.246 hisaddr = 208.236.238.6
Jan 25 22:06:01 kamikaze ppp[213]: Link: OsLinkup: 208.236.238.6
Jan 25 22:07:00 kamikaze ppp[213]: Phase: HDLC errors -> FCS: 1 ADDR: 0 COMD: 0 PROTO: 0

As is evidenced by the logs it fails during the handshake...never gets to
authentication.

Yes...I tried once _while_ using mpg123...didn't even skip.
