error opening sound device

[dansawyer]

All,

The system is a T41 with Fedora 7. Record and most features appear to work as documented. However attempts to play sound result in the above message. There is no other diagnostic. Any help on making this work?

If it any help mplayer works for root, but does not work for users. This is run as user.

Thanks,

Yes it errors with:

Expression 'ValidateParameters( outputParameters, outputDeviceInfo, StreamMode_Out )' failed in 'src/hostapi/oss/pa_unix_oss.c', line: 1206

One of the suggestions was to explicitly set alsa. How is this done?

Thanks - Dan

Thanks for the pointers. Now it plays, the meters work, however there is no output. Other sound still works.

What do you mean "there is no output"? When you are recording or when you try to play a track?

[dansawyer]

There is no sound output on play. Record works, the meters work, etc.

On play everything else appears to work including the meters, however no sound is produced, Output works on other sound packages.

Try using "ALSA Default" as the playback device instead of OSS
(select it in "Edit->Preferences->Audio I/O")

[dansawyer]

It was set to ALSA. The meters work and other sound works, mplayer, etc. However no sound.

That's weird - the error message that you are getting is to do with the OSS implementation of PortAudio.

This is going way over my head now, but there's some stuff about it here:
