Dear ALSA folks,
On a TUXEDO Book BU1406, the internal speakers stopped working. Sound still works when plugging in headphones or over HDMI [1]. This is reproducible with Linux 4.9 up to 4.11-rc6, and it worked a month ago, so I don’t think it’s a Linux kernel issue.
I assume it’s an hardware issue, that the for whatever reason, the system thinks headphones are plugged in all the time, and that the sensor(?) is damaged.
Can I somehow verify that with the output created by `ubuntu-bug audio`?I think the excerpt below is from PulseAudio, but shows `available: no` for the output speaker.
```
ports:
analog-input-internal-mic: Internes Mikrofon (priority 8900,
latency offset 0 usec, available: unknown)
properties:
device.icon_name = "audio-input-microphone"
analog-input-mic: Mikrofon (priority 8700, latency offset 0 usec,
available: no)
properties:
device.icon_name = "audio-input-microphone"
analog-output-speaker: Lautsprecher (priority 10000, latency offset
0 usec, available: no)
properties:
device.icon_name = "audio-speakers"
analog-output-headphones: Kopfhörer (priority 9000, latency offset
0 usec, available: yes)
properties:
device.icon_name = "audio-headphones"
hdmi-output-0: HDMI / DisplayPort (priority 5900, latency offset 0
usec, available: no)
properties:
device.icon_name = "video-display"
hdmi-output-1: HDMI / DisplayPort 2 (priority 5800, latency offset
0 usec, available: no)
properties:
device.icon_name = "video-display"
hdmi-output-2: HDMI / DisplayPort 3 (priority 5700, latency offset
0 usec, available: no)
properties:
device.icon_name = "video-display"
```
It’d be great, if you could tell me, what to look at, with the
headphones plugged and unplugged.
Kind regards, Paul [1] https://bugzilla.kernel.org/show_bug.cgi?id=194901
