# IMF plugin needs support for multiple audio configurations and not only 5.1 and 2.0 (https://ownzones.atlassian.net/browse/CD-8814)

---

**Use cases:**
- [x] multiple stereo tracks - e.g. **LtRtLtRtLRCLfeLsRs** :
https://connect.char.ownzones.dev/viaplay-plugin/packages/6bc752b4-52e2-4eeb-938d-e466209bcbdb

- [x] multiple surround tracks - e.g. **LRCLfeLsRsLRCLfeLsRsLtRt** :
https://connect.char.ownzones.dev/viaplay-plugin/packages/a854cdcc-35a6-4f96-8f28-decf01dda981

- [x] multiple stereo+surround tracks - e.g. **LRCLfeLsRsLRCLfeLsRsLtRtLtRt**:
https://connect.char.ownzones.dev/viaplay-plugin/packages/1128e01a-da2e-49c4-964b-9ffabd1b636b

- [x] channels arranged in a different order (within the same group - e.g. **RtLtLtRtRLCLfeLsRs**) https://connect.char.ownzones.dev/viaplay-plugin/packages/1128e01a-da2e-49c4-964b-9ffabd1b636b

- [x] skipped channels - e.g. **LCLfeLsRsxxLRCLfeLsRsLtRt** or others:
Skipped Stereo+Surround config: - https://connect.char.ownzones.dev/viaplay-plugin/packages/73577136-0601-4b65-9064-b671a38d1676
Skipped Surround config: xxxxxxLtRtLRCLfeLsRsLtRt - https://connect.char.ownzones.dev/viaplay-plugin/packages/f05f0502-1c86-45ed-b01d-58bdb79f65b5
Skipped - https://connect.char.ownzones.dev/viaplay-plugin/packages/959d1feb-0837-45ff-87a5-5b1fd716b6c0
configurations:
1) Skipped Stereo config: LRCLfeLsRsxxLRCLfeLsRsLtRt, LtRtxxLtRtLRCLfeLsRs,
2) Skipped Surround config: xxxxxxLtRtLRCLfeLsRsLtRt,
3) Skipped Stereo+Surround config: xxxxxxxxLRCLfeLsRsLtRt,
4) Skipped and switched channels: RtxLtxLtRtLRCLfeLsRs

- [x] mov+wav:
https://connect.char.ownzones.dev/viaplay-plugin/packages/6bc752b4-52e2-4eeb-938d-e466209bcbdb - Stereo + Stereo Wav
https://connect.char.ownzones.dev/viaplay-plugin/packages/6e47f7ef-3f09-4877-a3ad-ed88f35a091f - Stereo + Surround Wav

- [x] viaplay [source file](https://connect.char.ownzones.dev/viaplay-plugin/files/e9c67249-b874-4158-92fe-a236d84fdf3e) + LRCLfeLsRsLtRtLtRt - https://connect.char.ownzones.dev/viaplay-plugin/packages/503501fe-3da7-432d-8026-4efec20bec93
- [x] Check audio mapping for each configuration
- validations
- [x] incomplete audio config (e.g. LtLtRtLRCLfeLsRs - Rt is missing)
- [x] channels are not grouped (e.g. LtLtRtLRCLfeLsRsRt - we have all channels for 2 stereo&1surround but not grouped)
- [x] invalid audio config (e.g. audio config = some random text)
- [x] configuration with more channels than the source file - [Meridian_10sec_all_timeline tracks_mono.mov](https://connect.char.ownzones.dev/viaplay-plugin/files/8611dab0-1359-4337-aefa-dd866894dbba), audio config = *LRCLfeLsRsLRCLfeLsRsLtRtLtRtLtRt*

---
**Regression checks**
- basic configurations (LtRt, LRCLfeLsRs, LtRtLRCLfeLsRs, LRCLfeLsRsLtRt), skipped channels, validations, general plugin flow with both progressive&interlaced files
