[BUG] Regression: Failed to map card[0], port `analog-output-speaker` to a stream

[jmickelin]

Describe the bug

This seems to be a regression introduced by 5fb737c.

I can no longer switch output ports when the ports reside in different profiles. The error I get is as follows (I have added some extra debugging lines to showcase what happens):

[...]
DEBUG    .activate_port(0, analog-output-speaker)
INFO     # Card[0], port `analog-output-speaker` selected
DEBUG    .find_stream_port(...)
DEBUG      * card_port = analog-output-speaker, stream.ports = ['hdmi-output-0']
DEBUG      * stream: None
DEBUG    * Switching card[0] to profile `output:analog-stereo+input:analog-stereo` with priority 39333
DEBUG    .find_stream_port(...)
DEBUG      * card_port = analog-output-speaker, stream.ports = ['hdmi-output-0']
DEBUG      * stream: None
ERROR    Failed to map card[0], port `analog-output-speaker` to a stream
[...]

To Reproduce
Steps to reproduce the behavior:

1. Switch between outputs in the systray icon's menu
2. See error

Expected behavior
Output should be switched correctly.

Analysis
The problem seems to be that my computer's sound card only lists the ports in question when the corresponding profiles are active. That is, hdmi-output-0 is only active when a profile like output:hdmi-stereo+input:analog-stereo is active, and conversely analog-output-speaker and analog-output-headphones are only available when output:analog-stereo+input:analog-stereo is active.

This already seems to be what was addressed by 5fb737c, with these lines:

            # Try to find a matching stream
            stream = card.find_stream_port(port, self.sources, self.sinks)[0]

            # Switch profile if necessary
            if self.card_switch_profile(port, stream is not None):
                # Profile is changed: retry searching for the stream
                stream = card.find_stream_port(port, self.sources, self.sinks)[0]

However, as shown by the logging I added to card.find_stream_port, the contents of self.sinks is never updated after switching profile! This stale information of course causes the second lookup to fail, just like the first one did.

It seems prudent to force a refresh of the Pulseaudio data from within card_switch_profile. I have confirmed that adding the following in that function resolves the issue:

Any progress on this? This issue depreciated the AUR package.

[yktoo]

@jmickelin Thanks for investigating this and sorry for the late response. Here you refer to ports:

The problem seems to be that my computer's sound card only lists the ports in question when the corresponding profiles are active.

whereas further on you mention the sink list that doesn't get to be updated:

However, as shown by the logging I added to card.find_stream_port, the contents of self.sinks is never updated after switching profile!

Did I understand you correctly that in this second excerpt you refer to sink ports that are supposed to be re-read?

Besides, update_all_pa_items() updates each and every PA object. So should the problem indeed lie in the port list, I'd prefer to use a more targeted method for the update.

On a side note, PulseAudio issues like this one are extremely hard to properly analyse because they depend on specific devices, PA modules in use, and even on the PA version.

[yktoo]

@alsimoneau What do you mean with "depreciated the AUR package"? This issue doesn't seem to be package-specific, rather a device-specific one.

[alsimoneau]

Here's the link to the AUR package: https://aur.archlinux.org/packages/indicator-sound-switcher

As you can see here, it's flagged as out-of-date because of this issue.

[yktoo]

@alsimoneau The comment there states:

Need to change from legacy dependency 'libappindicator-gtk3' to 'libayatana-appindicator'; also revert a commit that introduced a regression: #132

Not sure we can call it a "regression", it's more of an incomplete fix.

As for the change "from legacy dependency 'libappindicator-gtk3' to 'libayatana-appindicator'", that doesn't seem to be correct as it Depends on gir1.2-ayatanaappindicator3-0.1 | gir1.2-appindicator3-0.1.

UPDATE: I see that the AUR package has a few incorrect dependencies indeed; however it's been submitted by someone else so I can't maintain it.

[yktoo]

I've (seemingly) resolved the issue by enforcing a stream update after a profile switch. However to be honest, the change doesn't sit right with me as it looks more like a workaround rather than a solution.

If we look closely to your logs, we can see that the streams and ports do get updated as a result of PulseAudio event handling. Here's an excerpt starting with an output item click:

DEBUG    .activate_port(0, hdmi-output-0)

DEBUG        * Activated sink port `hdmi-output-0`
[...]

The problem is actually not so much in the (lack of) update, but rather that the app tries to find a stream/port immediately upon a profile switch; PulseAudio fires change events a short while later, and they get properly handled, resulting in registering a newly available port.

If I'm correct, the output will always be selected on a second click; and I can confirm it works that way for me indeed.

Hence the proper solution would be to wait until PA event handling is finished, and then to try remapping the streams. Will need to ponder a bit more over that...

[yktoo]

I decided to go ahead and release this in 2.3.10. The issue seems too complicated to be properly resolved without update duplication: PulseAudio issues events asynchronously and there's basically no way to know how many events to expect or if a certain event is the last one.
