各位大佬好，我刚接触Ubuntu不久，最近遇到了一个头疼的音频问题：之前用22.04 LTS的时候内置声卡完全正常，但自从给笔记本配对了一个蓝牙设备之后，音频就只能通过蓝牙播放了，其他情况都显示Dummy Output，内置声卡完全没反应。

我已经试过了各种能找到的办法——比如重装pulseaudio、重启音频服务、折腾Alsa、安装sof-firmware，但都没解决问题，甚至为此升级到了22.10（Kinetic），结果还是一样。现在实在没辙了，来这里求助，需要我运行任何命令提供信息都可以，麻烦各位帮忙看看！

目前我的系统是Ubuntu 22.10 Kinetic，先放一下inxi -A的输出：

Audio:
Device-1: Intel Comet Lake PCH-LP cAVS driver: snd_hda_intel
Sound Server-1: ALSA v: k5.19.0-31-generic running: yes
Sound Server-2: PipeWire v: 0.3.58 running: yes

后来我在网上查资料，感觉自己的问题和类似案例匹配，之后又运行了inxi -xxz --audio，输出如下：

Audio:
Device-1: Intel Comet Lake PCH-LP cAVS driver: snd_hda_intel v: kernel
bus-ID: 00:1f.3 chip-ID: 8086:02c8
Sound Server-1: ALSA v: k5.19.0-31-generic running: yes
Sound Server-2: PulseAudio v: 16.1 running: no
Sound Server-3: PipeWire v: 0.3.58 running: yes

我尝试启用PulseAudio：
systemctl --user enable pulseaudio
这一步成功了，但接着启动服务的时候：
systemctl --user start pulseaudio
就报错了，提示：

Job for pulseaudio.service failed because the control process exited with error code.
See "systemctl --user status pulseaudio.service" and "journalctl --user -xeu pulseaudio.service" for details.

下面是这两个命令的详细输出：

我一直在找能成功启动PulseAudio的办法，但至今没进展，恳请各位大佬帮忙指点，谢谢大家！
