Ref below. In that case if your referring to packet via a tnc,
I concede yes its just as error free as Pactor or any other mode
useing a TNC. Useing a sound card only with soundcard software
however sounds very implausable to me!!!

Packet with a sound card uses exactly the same protocol as packet with a
TNC - AX25. Therefore it uses a CRC exactly the same as packet with a TNC.
