That is a possibility, you can verify by checking to see if there is DC across your speaker. Or see if you have DC on the speaker terminals with no speaker connected. Also please check both of the diodes and associated resistors in the bias network, these are famous for shorting/going out of tolerance and messing up the bias voltages... not good for the outputs.
