The remarks about input d.c. bias are very important, and it sounds like with a volt the circuit basically works. Note however that the 50 ohm resistor is now pulling about 20mA all day long. The 324 can supply this, but each section doing that will dissipate (12V - 1V)*20mA = 220mW (minimum) which will warm things up considerably. If this is for stereo audio then we'll have at least 440mW to handle. That's within ratings for a 25C ambient, but it will be getting warm.
The other drawback is that with that stiff loading the loop gain of the second section will be reduced appreciably --- exactly how much depends on 324 internal circuit details. Since the devices that provide a positive output current are compound emitter followers ("darlington"), this may not be horrible. But this loading will most likely entail a signficant increase in distortion, particularly at high frequencies where one is running out of loop gain.
However, there is one advantage. The 324/358 family is notorious for having high crossover distortion. It's been a long-standing technique to pull enough current from the output, typically by loading to "ground", to force the output stage into class A operation, thus dodging the crossover distortion. Although I've never seen anything as aggressive as 50 ohms, it may work adequately.
By coincidence, recently a client had me look at a microphone filter circuit also using such opamps. The circuit had several problems besides, but the designer(s) asked for even more gain --- a whopping 34dB per filter section, and had no loading to reduce crossover distortion. Overall, a very poor audio design.
