Description Greg Woods 2020-08-02 16:09:08 UTC

User-Agent:       Mozilla/5.0 (X11; Fedora; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.97 Safari/537.36
Build Identifier: 

I have an ASUS Xonar SE card which has an iec958 device (optical/TOSLINK). I try to send sound to the device with:

aplay -vv -D iec958:CARD=SoundCard,DEV=0 /path/to/wav/file

I can see the VU meter bouncing up and down, but no sound is produced and the optical cable is not lit (I have tried another cable with the same result).

The device shows as recognized and on:

$ amixer -c0 contents
[...]
numid=19,iface=CARD,name='IEC958 In - Output Jack'
  ; type=BOOLEAN,access=r-------,values=1
  : values=on

The referenced URL points to a thread from the Fedora Users list where someone far more knowledgeable than me regarding ALSA helped determine that this is probably a bug. The device driver shows the device should work, but it doesn't.

The card in question is one that has a USB bus chip on it plus a USB audio chip:

$ lspci
[...]
01:00.0 USB controller: ASMedia Technology Inc. ASM1042A USB 3.0 Host Controller

$ lsusb
[...]
Bus 003 Device 002: ID 0b05:189d ASUSTek Computer, Inc. Xonar SoundCard

The referenced Fedora Users list thread contains all of the ALSA-related commands that were run to diagnose and test this.


Reproducible: Always

Steps to Reproduce:
1.Attempt to play a sound file through the IEC958 device on the ASUS Xonar SE sound card
2.
3.
Actual Results:  
No sound is produced and the optical cable is not lit, although the device shows as present and active, and the VU meter shows that the application is sending sound.

Expected Results:  
Sound should be produced, optical cable should be lit.

Comment 1 Fedora Program Management 2021-04-29 17:05:22 UTC

This message is a reminder that Fedora 32 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora 32 on 2021-05-25.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained. At that time this bug will be closed as EOL if it remains open with a
Fedora 'version' of '32'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 32 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Comment 2 Ben Cotton 2021-05-25 17:46:38 UTC

Fedora 32 changed to end-of-life (EOL) status on 2021-05-25. Fedora 32 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
