No problem! That's odd though - the advertised SNR for that card is 116dB. Do you have multiple rigs that are all giving you the same reading?
I tried on two setups, and they both give similar values of max 75-95 dB across frequencies. I couldn't find information about how much my speaker driver amplifies the signal, so it might be that its gain is not high enough to appreciate 116dB SNR. I think we rarely use volumes higher than 75 dB for experiments, so this is probably good enough.
Thank you again for your help!
