Description Geert Janssens 2015-11-05 20:50:48 UTC

I'm on Fedora 22 and have set up an rdp session to a Windows XP vm via krdc. On Fedora xfreerdp is used as rdp backend.

The connection settings in krdc allow three ways to handle the remote pc's sound: play it on the local (client) pc, play it on the remote pc or disable sound.

My goal is to play sound on the local pc. I can't make this work with any of the above options.

The krdc version on Fedora 22 is not in the default list for the krdc component on bugs.kde.org, so I'll specify it here:
krdc-15.04.0-1.fc22.x86_64

Reproducible: Always

Steps to Reproduce:
1. Use krdc to connect to a remote Windows XP machine
2. In the connection settings choose "On this computer" for the sound setting
3. Start the remote connection
4. Make some sound on the remote pc (for example by adjusting the sound volume)


Actual Results:  
No sound is heard on the local pc


Expected Results:  
The local pc properly reproduces the sound emitted on the remote pc


Krdc delegates the actual remote connection to xfreerdp. For sound it passes either of these options:
/audio-mode:0 (for sound on this computer)
/audio-mode:1 (for sound on remote computer)

When I run xfreerdp manually without this option and instead add "/sound:sys:pulse" or "/sound:sys:alsa" sound is properly reproduced on the local machine.

Comment 1 Urs Wolfer 2015-11-06 17:39:29 UTC

Can you reproduce this issue when you start xfreerdp from command line (with the correct parameters)?

Comment 2 Ryan Gillette 2015-11-15 07:30:38 UTC

I can confirm that using KRDC that I get no sound from Windows VM. When I launch from command line with "xfreerdp /u:username /p:SuperSecretPassword /v:MyCoolIP /sound:sys:pulse /w:1440 /h:900" I get sound from the VM just fine.

Fix the rdp audio issue

I've tested the patch on my qemu vm(win10), both options work for me.

krdc(7127)/krdc (RDP backend) RdpView::start: Use FreeRDP 1.1+ compatible arguments
krdc(7127)/krdc (RDP backend) RdpView::start: Starting xfreerdp with arguments:  "-decorations /w:1816 /h:1247 +smart-sizing /kbd:0x00000409 /u:acelan /parent-window:153092138 /bpp:24 /audio-mode: 0 /sound:sys:alsa /drive:media,/home/acelan /network:lan /rfx /cert-ignore +clipboard /port:3389 /v:192.168.2.118"

and

krdc(7127)/krdc (RDP backend) RdpView::start: Use FreeRDP 1.1+ compatible arguments
krdc(7127)/krdc (RDP backend) RdpView::start: Starting xfreerdp with arguments:  "-decorations /w:1800 /h:1231 +smart-sizing /kbd:0x00000409 /u:acelan /parent-window:153092217 /bpp:24 /audio-mode: 0 /sound:sys:pulse /drive:media,/home/acelan /network:lan /rfx /cert-ignore +clipboard /port:3389 /v:192.168.2.118"

Comment 4 Tom Chiverton 2016-08-22 19:23:38 UTC

Ack on 16.04 LTS.

krdc runs
#  xfreerdp -decorations /w:1024 /h:768 /kbd:0x00000809 /u:administrator 
/parent-window:25166409 /bpp:24 /audio-mode:0 /drive:media /tmp 
/network:broadband /rfx /cert-ignore +clipboard /port:3389 
/v:ispring.evcloud.co.uk /p:

But this works
# xfreerdp /u:administrator /v:ispring.evcloud.co.uk /sound:sys:pulse 
/w:1024 /h:768 /bpp:24 /drive:media /tmp /network:broadband /rfx 
/cert-ignore +clipboard

Comment 5 AceLan Kao 2016-08-23 03:15:49 UTC

Tom, 
Are you saying that the krdc/rdp on 16.04 doesn't work?
Can you also provide the krdc version on 16.04?
Thanks.

Comment 6 Tom Chiverton 2016-08-23 18:50:15 UTC

16.04 uses KRDC Version 4.14.16 with KDE Development Platform 4.14.16

Comment 7 Tom Chiverton 2016-08-23 18:51:03 UTC

And, yes, no audio with the command line KRDC uses (as seen in ps). Making the change suggested and invoking by hand sounds works fine.

Comment 10 Geert Janssens 2022-11-08 12:23:46 UTC

For me this is fixed. I'm currently running Fedora 36, which ships freerdp-2.8.0-1.fc36.x86_64.

For my part this can be closed, though I don't know if that's something I should do now or leave for the maintainers. So I have set the status back to reported to be on the safe side.
