我的v25每次重启后网页播放几乎没有声音，必须手动控制音量大小后才能恢复

这个问题内部已经有问题单在跟踪，我们催下研发进度

把默认的PipeWire 切换到 PulseAudio，待后续问题解决再切换回来。

在主目录新建一个audio-switch.sh文件，文件内容：

#!/bin/bash

# Deepin 25 音频服务切换脚本
# 在 PipeWire 和 PulseAudio 之间切换

set -e

# 颜色定义
RED='\033[0;31m'
GREEN='\033[0;32m'
YELLOW='\033[1;33m'
BLUE='\033[0;34m'
NC='\033[0m' # No Color

# 日志函数
log_info() {
    echo -e "${BLUE}[INFO]${NC} $1"
}

log_success() {
    echo -e "${GREEN}[SUCCESS]${NC} $1"
}

log_warning() {
    echo -e "${YELLOW}[WARNING]${NC} $1"
}

log_error() {
    echo -e "${RED}[ERROR]${NC} $1"
}

# 检查当前音频服务
get_current_audio_server() {
    if systemctl --user is-active --quiet pipewire.service || systemctl --user is-active --quiet pipewire-pulse.service; then
        echo "pipewire"
    elif systemctl --user is-active --quiet pulseaudio.service; then
        echo "pulseaudio"
    else
        echo "unknown"
    fi
}

# 显示当前状态
show_status() {
    local current=$(get_current_audio_server)
    log_info "当前音频服务: $current"
  
    echo -e "\n服务状态:"
    echo "PipeWire: $(systemctl --user is-active pipewire.service 2>/dev/null || echo 'inactive')"

    show_status
else
    main "$@"
f

使用方法
保存脚本：将上面的脚本保存为 audio-switch.sh
赋予执行权限：

chmod +x audio-switch.sh

使用脚本：

# 查看当前状态
./audio-switch.sh status

# 切换到 PulseAudio
./audio-switch.sh to-pa

# 切换到 PipeWire  
./audio-switch.sh to-pw

# 重启当前音频服务
./audio-switch.sh restart

第一次切换到PulseAudio，会提示失败，然后重启在切换一次PulseAudio，就可以成功。
