If the card can't keep its frequency stable, it will sound like a tape deck which can't move the tape at constant frequency. For voice, pauses between sentences and/or turn taking will take care of even large frequency deviations. For music, you probably don't want to listen to a card that can't keep pitch... Given how cheap crystal oscillators are, I'm amazed that people build cards that can't stick to a nominal frequency. (All useful frequencies are multiples of either 8000 or 11025 Hz, it seems.)
