I can not hear nintendo switch from obs

[kingsmamn]

so I bough capture card recently and tried to connect to my computer and it worked perfectly including sound, but next day I could not hear any sound even I tried all things possible, include disconnecting all the plugs and code or resetting obs. Help me please. The only problem is sound. Everything else works perfectly fine. When I change dp(my computer) to hdmi which is nintendo switch and connected through capture card, it all works so fine include sound but just only in obs. I'm so wondering because it worked like 3 weeks ago. Here's my log file https://obsproject.com/logs/G7LlbNNGjt3atPVH
