[BUG]: Audio data received but not played in Linux environment

[Tomato-in]

Description

Audio data received but not played in Linux environment

Reproduction

Environment

• OS: Ubuntu 22.04.5 LTS
• Pot Version: 3.0.6
• Audio System: PulseAudio 15.99.1

Issue Description

When clicking the pronunciation button in Pot, the application successfully fetches audio data but fails to play it. This happens consistently regardless of the translation service being used (tested with Youdao Dict, DeepL, etc.).

Observed Behavior

1. Pot successfully connects to PulseAudio (confirmed via strace logs)
2. Pot successfully fetches audio data from the translation services (e.g., received 32074 bytes of audio data)
3. However, no audio is played, and no audio-related system calls are made after receiving the data

Expected Behavior

The audio should be played through the system's audio output after the pronunciation button is clicked.

Investigation Details

1. System audio works correctly (tested with paplay)
2. Pot connects to PulseAudio successfully:
   connect(..., "/run/user/1000/pulse/native", ...) = 0
3. Audio data is successfully received, but no subsequent audio processing occurs:
   [DEBUG][hyper::proto::h1::conn] incoming body is content-length (32074 bytes)
4. No audio-related system calls are made after receiving the data, suggesting the audio processing pipeline might be broken

Additional Notes

• Opening pavucontrol sometimes temporarily resolves the issue, suggesting this might be related to how Pot handles the audio stream setup
• Other applications' audio works normally
• All audio devices show as SUSPENDED in pactl output, but this is normal behavior and other applications can wake them up correctly
