Sound Broken in 5.4.30 for Pi3

[J1mbo]

We noticed that RDP audio isn't working with 5.4.30 (was working with Pi3 beta, 5.4.18 based I think). Logs show this:

Code: Select all

usbcore: registered new interface driver snd-usb-audio
     hardware.cpp ( 1095): -- ERROR -- INTERNAL ERROR. Please, contact WTware tech support.
     globalConfig.cpp ( 1631): -- ERROR -- INTERNAL ERROR. Please, contact WTware tech support.
 ERROR: Sound card not found. Disable sound.

Here is the (working) log from 5.4.18:

Onboard sound at RPi should be enabled in config.txt at SD card now.

[J1mbo]

Thanks, so it is:

# Enable onboard audio (HDMI or jack).
dtparam=audio=on

[kmen]

and the sound option should be on?
sound=on

[J1mbo]

Yes. To edit config.txt, you can use a browser, http://[terminal-ip]/

[mstorck]

I have set

Code: Select all

sound=on

in configuration file. I also set

Code: Select all

dtparam=audio=on

in config.txt and finally I also set

Code: Select all

hdmi_drive=2

in config.txt. But I still have these log entries:

Code: Select all

and of course no audio/sound within an RDP session.
I'm running

Code: Select all

WTware v.5.4.40/RPi supervisor.

on RPi3.
Another ThinClient OS for RPi has working sound on the same hardware.

Any ideas to get this working with WTware?

Please, send me whole log and all files on SD in zip to aka@pxe.ru

Hi, all~

I came across this thread as I was having issues getting audio out of the audio jack for my Pi3 when running WTware.

The eventual combination of settings that did the trick for me, in the config.txt file, were:

Code: Select all

# hdmi_drive  result
# 1           Normal DVI mode (No sound)
# 2           Normal HDMI mode (Sound will be sent if supported and enabled)
hdmi_drive=1

# Setting this to 1 pretends that all audio formats are unsupported by the display.
# This means ALSA will default to the analogue audio (headphone) jack.
hdmi_ignore_edid_audio=1

# Enable onboard audio (HDMI or jack).
dtparam=audio=on

# Enable improved audio driver
# https://www.raspberrypi.org/forums/viewtopic.php?f=29&t=136445
audio_pwm_mode=2

...just thought I would share for others that might run in to a similar issue.

P.S. For completeness, my config file looks simply like:

Code: Select all

server=--new--
graphic=adf
sound=on
sound_rate=44100
sleep=20
connect_timeout=5
