Public bug reported:

[Summary]
On my Lenovo XiaoXinPro-16-IMH9 running Ubuntu 24.04 LTS, the entire audio system crashes when I start the Android Emulator. This happens with the default PipeWire audio server. The system audio goes completely silent.

[Steps to Reproduce]
1. Use a fresh installation of Ubuntu with the default PipeWire audio server.
2. Install Android Studio and set up an Android Virtual Device (AVD).
3. Start the AVD from Android Studio or the command line.

[Expected Result]
The Android Emulator should start and have audio, and the system audio should continue to work normally.

[Actual Result]
As soon as the emulator starts, the entire system audio crashes. The key error message in the journalctl log is a repeating line:
"spa.alsa: hw:sofhdadspp: (...) snd_pcm_avail after recover: Broken pipe"

[Workaround / Additional Information]
The issue is 100% reproducible. I have found a workaround that completely solves the problem. By forcing the kernel to use the legacy HDA driver instead of the SOF driver, PipeWire works perfectly with the emulator.

This is achieved by creating a file `/etc/modprobe.d/alsa-fix.conf` with the following content:
"options snd_intel_dspcfg dsp_driver=1"
After running `sudo update-initramfs -u` and rebooting, the problem is gone.

This strongly suggests a stability bug in the Sound Open Firmware (SOF)
driver for this specific hardware when used by PipeWire's default low-
latency configuration. Switching back to PulseAudio also works around
the issue, likely due to its different latency model.
