Written by AMS2 cockpit audio missing OBS is the exact bug now being discussed on the official Reiza Studios forum: a reproducible issue where certain cockpit sounds simply don’t make it into OBS Studio recordings of Automobilista 2, even though everything sounds completely normal during actual gameplay. The report, posted against version 1.6.9.91, points to a specific capture-side quirk rather than a general failure in the sim’s own audio engine. For simracers who stream or record their sessions, it’s a bug worth understanding before it shows up unnoticed in a saved clip.
What’s Behind the AMS2 Cockpit Audio Missing OBS Bug
The original poster describes losing lower cockpit audio — things like the ignition sequence, the start tone, and parts of the engine note — when using OBS’s application-specific audio capture on certain cars. The sim itself sounds fine when played normally; the problem only surfaces once OBS is set to record or stream the session. Switching to a generic device capture, such as grabbing audio straight from the headset output, restores the missing sounds. That distinction is the core of the report: it’s not that Automobilista 2 stops producing the audio, it’s that OBS isn’t picking all of it up under one specific capture method.
The issue was first tested on Formula cars, then confirmed on a V-10-engined machine, showing it isn’t limited to a single vehicle class. Reiza’s own forum thread remains the primary source for these reports so far, and it’s worth following alongside Simracing.Fan’s ongoing Automobilista 2 coverage for any follow-up from the studio.
What Drivers Are Reporting
Two separate posts in the thread describe slightly different flavors of the same underlying problem. Both agree the sim’s own audio playback is unaffected — this is purely a capture-side issue tied to OBS Studio and how it grabs audio streams from Automobilista 2 on Windows.
Missing Cockpit Audio Symptoms
The original poster’s account is the more specific of the two: certain sounds vanish entirely from the OBS recording, even though they’re audible in-game. The examples given are the ignition/start tone and portions of the engine audio when driving Formula cars, later reproduced with a V-10 car as well. The sounds aren’t quiet — they’re simply absent from the captured track when OBS uses application-specific capture.
Lower/Attenuated Audio Symptoms
A second forum member, HookinFell, reports a broader version of the problem: rather than specific sounds disappearing, the cockpit audio comes through noticeably weaker across every car tested, spanning both historic and modern content in Automobilista 2. This points to a bug that isn’t confined to one narrow trigger and could vary in severity depending on car, audio setup, or OBS configuration — a detail the thread hasn’t pinned down yet.
| Reporter | Symptom | Cars Affected | Workaround Found |
|---|---|---|---|
| Original poster | Specific sounds (start tone, engine segments) missing entirely | Formula cars, one V-10 car | Switch OBS to generic device capture instead of application-specific capture |
| HookinFell | Cockpit audio generally quieter/attenuated | All cars tested, including historic and modern | Not specified |
Possible Causes Behind the Bug
Nobody in the thread — including Reiza staff — has pinned down an official technical explanation yet, but the pattern reported points toward how OBS interacts with the sim’s audio output rather than a fault in Automobilista 2’s own sound engine. Automobilista 2’s internal Audio Engine handles cockpit audio through a dynamic, multichannel system: engine notes, transmission whine, and lower-frequency mechanical sounds are often routed separately rather than mixed into a single output.
OBS’s application-specific audio capture works by hooking into a program’s audio session on Windows, and that method doesn’t always grab every channel or audio stream a game produces, especially when a game splits sounds across multiple internal buses. If the Audio Engine sends certain cockpit sounds through a different audio path than the main mix, an application-capture hook in OBS could miss them while a full device capture — which grabs everything reaching that audio output, headset or speakers — picks up the complete mix.
That’s consistent with what the original poster found: switching capture method fixed the problem without changing anything in the sim itself. It points at a capture-compatibility issue between the two pieces of software rather than a bug in AMS2’s sound design, though this remains unconfirmed since no developer has commented on the technical root cause yet.
Community Workarounds Shared So Far
Only one concrete workaround has surfaced in the thread, and it comes from the person who first reported the bug:
Switching from application-specific capture to generic device capture (e.g., capturing the headset output directly) in OBS restores the missing cockpit audio.
For streamers and content creators running Automobilista 2 sessions, that’s a practical fix worth testing if a recording comes out with thin or missing cockpit sound:
- Open OBS Studio‘s audio source settings for the AMS2 capture.
- Switch from application-specific capture (capturing the game’s process directly) to a generic audio device capture pointed at your headset or speaker output.
- Re-record a short test clip with the same car and compare cockpit sound presence against the previous setup.
- If cockpit audio is present but still sounds thin, note the car and track so the detail can be added to the forum thread.
HookinFell’s broader “audio is just quieter everywhere” report doesn’t come with a confirmed fix in the thread. Anyone hitting attenuated rather than missing sound may need to try the same capture-method swap and report back on the result, since it hasn’t been explicitly verified for that variant of the issue.
Why This Matters for Simracing Content Creators
For anyone building a channel around Automobilista 2 gameplay, audio fidelity is part of the product: viewers expect to hear ignition sequences, gear shifts, and engine notes exactly as they sound in the cockpit. A bug that silently strips or dampens those sounds during OBS Studio capture can undercut a stream or a highlight reel without the creator ever noticing until after the session ends, since the sim itself never signals a fault. That’s part of why Simracing.Fan tracks community-reported bugs like this one closely, alongside its broader OBS streaming setup coverage, because these capture-side quirks tend to affect any title using similar audio session hooks, not just Automobilista 2. Until Reiza Studios or the OBS Project team confirms a root cause, the safest approach for streamers is testing capture settings before a session that matters, rather than discovering thin or missing cockpit audio after the fact.
Reiza Studios’ Response and Status
As of this writing, the thread has drawn only two user replies, and there is no confirmation from Reiza Studios that this has been logged as an official bug. The forum post itself sits in what functions as a bug-report area, but nothing in the discussion indicates a developer has replied, acknowledged the cause, or scheduled a fix. That means the capture-method workaround remains a community-tested fix rather than an officially sanctioned solution, and the underlying cause — whether it’s an OBS limitation, an Automobilista 2 audio routing quirk, or a combination of both — is still unconfirmed.
Simracers who record or stream Automobilista 2 and notice similar symptoms may want to check the thread directly and add their own configuration details, since more reports could help Reiza’s team reproduce and address the issue with an official response.
FAQ: OBS Audio Issues in AMS2
Is this an Automobilista 2 bug or an OBS bug?
It’s unconfirmed. The evidence so far suggests it’s a capture-compatibility issue between OBS’s application-specific capture method and how AMS2 routes cockpit audio, but no developer has confirmed the exact technical cause.
Does the sim’s own audio sound broken while playing?
No. Both reports describe the sound being normal during actual gameplay; the problem only appears in the OBS-captured recording.
Which cars are affected?
The original report covers Formula cars and a V-10 car. HookinFell’s broader report describes reduced cockpit audio across all cars tested, including historic and modern content, so it may not be limited to a specific class.
Is there a fix?
One workaround has been shared: switching OBS’s audio capture from application-specific capture to generic device capture (e.g., capturing your headset output) restored the missing sounds for the original poster. This hasn’t been confirmed to fix the broader “quieter audio” symptom reported by HookinFell.
Has Reiza Studios responded?
Not yet, based on the current state of the thread. Only two community replies are present, with no developer confirmation of the bug or its cause.
Should I report my own case?
If you’re capturing Automobilista 2 with OBS Studio and notice missing or weak cockpit audio, adding your setup details to the existing forum thread could help Reiza’s team identify a pattern and prioritize a fix.
