Audio on playback losing quality

[bora]

Hey I am using pro tools 10 on windows 10 with asio driver. My problem is the audio on playback loses low end becomes low quality weak sounding after the first few plays. So I'll make a take and play it a few times and all the sudden things start sounding low quality losing lots of bass/lows. If I stop playing anything on pro tools it might work again after few minutes . I have monitored my cpu usage and it seems to stay below 10%. This does happen when I have plugins running but i experimented turning them off and still same result. I messed with my hardware buffer does not seem to help. I tried using different speaker thats not the problem either. It happens at random times. Sometimes it will work great for 10 minutes but then I just fall back to this problem. I do not think it is a asio4all problem because I have tried all sorts of settings on there and no fix. Also tried different compatibility modes. Please help

Thanks
