Subject: [PATCH] perf(sound): remove blocking delay in audio device switching
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Remove the 200ms blocking sleep (QThread::msleep) that was originally
used for debouncing multiple signals during device switching. Analysis
shows that valid signals arrive with sufficient intervals (>250ms),
making the blocking delay unnecessary and harmful to UI responsiveness.

移除音频设备切换中的阻塞延迟

移除原本用于防抖多个信号的 200ms 阻塞延迟（QThread::msleep）。
分析表明有效信号到达的间隔已足够大（>250ms），使得阻塞延迟既不必要
又损害 UI 响应速度。
