No sound when plug slate PC into base

[Prevet]

I have a slate tablet and the sound works with OpenBSD, except it is a little weird in that it comes out of the microphone jack instead of the speakers. It did the same on Linux.

It only has two USB ports so I got a dock for it, which is a base that it plugs into which raises it up off the table and provides3 additional USB ports, a power plug, head phone jack, microphone jack, RJ-45 Ethernet and a VGA connector for an external monitor. All of these connections work except it stops making any sound. Is it possible to fix this?

dmesg without the base and the sound is working:

It seems like your tablet automagically reroutes audio to the base when it's plugged in.

Something like

$ sndiod -s default -f snd/1

might help, but that's a total stab in the dark based on the above info.

[Prevet]

I popped it open and its just a plug at the base of the tablet that connects to a plug on the dock and then its just some wires going to the back of the unit. So apart from the additional USB connections its just a glorified extension cable in a box.

"$ sndiod -s default -f snd/1"

Thanks. That didn't do anything unfortunately.

I tried using the old Microsoft tablet XP restore disks to see if it works, but it said the operating system restore program won't start in DOS (So you need Windows installed to restore the Windows OS? Funny stuff.), so I will try lubuntu to test the cable.

All the guides for Linux said they could not get the speakers working. I got them working for a brief shining moment, but then they stopped working after a reboot but I couldn't remember what I did that made them work. That was using Alsa MIxer, I assume OpenBSD uses something else? I'd much rather have the tablet's onboard speakers working if that was possible.

cmixer is similar.

Thanks.

I installed lubuntu and got the sound working through the speakers using alsamixer, which is what I really wanted, so I'll try to convert those settings to cmixer. If I can't do it I'll post again in the hope someone here can translate alsa settings to cmixer.
