X60s, T60 and T40 have lost audio under ubuntu!

[John H]

It's unanimous! My X60s, T60 and (now) the T40 all have NO audio on the ubuntu partition, but it works on the XP partition!

I don't get it. Each has a different ubuntu and each has a different history and a different use.

The ONLY common thing I can think of is that at different times I've tried to get the dialup 'winmodem' working on each, and I suspect that 'winmodems' share something with the audio system.

I have no idea how to proceed with debugging.

If I could I'd replace a winmodem with a standard 16550 type complete modem, and replace the audio card with something else, but I'm not sure it can be done.

This is getting frustrating. I've got to solve the problem so I don't have to port a movie to XP to watch it.

As usual, check /var/log/messages to see the error messages.

If you haven't already, try configuring pulseaudio

As usual, check /var/log/messages to see the error messages.

I looked, there's about 2222 lines of output in the last 5 days, and scanning for 'audio' I found several entries like this:

Mar 8 05:59:02 JHX60s pulseaudio[2029]: ratelimit.c: 118 events suppressed

whatever that means.

Mar 8 05:59:02 JHX60s pulseaudio[2029]: ratelimit.c: 118 events suppressed

Its suppressing reoccuring error messages in order to not flood the log. The interesting message is the one before the suppressing starts...

In all likelyhood, pulseaudio can't communicate with your audio chip. Either the driver broke (recent kernel upgrade?) or something else hogs the device (what do you mean with winmodem, did you install anything? Its true that the intel hda does sound and modem at the same time)

Well, here's a few lines of stuff before the one containing 'audio':

Thats just the log from resuming from suspend. Its further up. How about you do a fresh reboot, that'll narrow it down to about 1000 lines of logfile.

There seems to be a bug related to this -

Well! The X60s audio is working!

I discovered the pulseaudio volume control and by fiddling with a device dropdown it started working.

Hooray.

Not only that but afterwards the Audio Angel flew over my T60 and IT'S audio started working!
