Distorted Audio in 1.0.0

[mattclaw]

Thanks for the great product. I've actually spent the past 2-3 years searching for NOS GCN ODEs, so when I found your thread on gc-forever I was so excited by the prospect of you shipping. What a nice surprise that you were able to partner with Dan to launch the GC-Loader! I'm loving it so far and I've only had it installed ~24 hours.

I updated GC-Loader tonight to 1.0.0 and played a few games. Of the three I played, I had two instances of glitchy background music where the audio was distorted and noisy for a brief period, but overall effects and background music sounded fine throughout the rest of the games' sessions. The 3rd game, Chibi Robo, exhibited no issues during my ~30 minutes of play.

In Wave Race - Blue Storm (USA), I have been able to reproduce this between cold boot at the character select screen of the "Free Ride" mode. The first time I encountered it was while scrolling from the 1st character to the 2nd character (David Mariner) in the list; the initial playback of his background music was corrupted, but after changing to another character and back, subsequent playback of the audio was fine. After turning the system off and back on, booting into the game, and returning to that screen, it took me a minute or so to reproduce the distortion by erratically cycling through characters.

The other affected game was Super Monkey Ball (USA) which had glitched audio after completing the 10 beginner levels when it plays a celebratory sequence. I've not yet had a chance to attempt to replicate this instance. However, the corruption in the audio was similar in nature to that found in Wave Race.

Swiss r756 was used to boot all titles All ISOs were trimmed with NKit v1.4 and have been verified to be known good dumps against a popular database.

I only just installed the GC-Loader late last night, so I hadn't put much time in on the previous version and only played these 3 games tonight. I'll update this issue if I encounter others.

I am not quite sure if this is a Swiss issue or a GC-Loader issue, so please forgive me if I've opened this issue in error.

[danielkraak]

Thanks for reporting the issue. I will look into it.

Tested with swiss r766 on a pal dol 001 gamecube with gcloader,still no streaming audio,i'm on latest firmware with gcloader. All my games are full iso's.

[danielkraak]

Could you explain more specifically what you mean with 'no streaming audio'? Are you encountering issues with certain games? Or all games?

[fille1976]

Testing games now with swiss r766 Will test games from a list. What is working is 1080 Snowboarding (ok) Eternal Darkness (ok) Bomberman Generation (ok) Crash Bandicoot Wrath Of The Cortex(No Music in Intro),in game no voice of characters Dave Mirra Freestyle Bmx 2 (ok) Fantastic Four (ok) Geist (ok) Smugglers Run (No audio play at start screen) Star Fox Adventures (ok) Ikaruga (ok) Lost Kingdoms (ok) X-Men Legends (Distortion in the sound start screen) Judge Dredd (No audio in game,also in intro) Super Monkey Ball (No audio when demo is running) and start screen) Splinter Cell Pandora Tomorrow (No audio at start screen) Tak And The Power Of Juju (No audio at start screen) So some games are not working correct,others are fine,can also be a swiss problem.

[danielkraak]

Thanks for the list. It seems like an audiostreaming issue. I will verify your issues and look into a fix.

[fille1976]

I will test more games in the next days and report problems here. Games are from redump.

I have also run into the distorted audio in Mario party 6 and 7. Was instructed to flip dip switch 4 to go to slower read mode and that has solved the audio issue in those games.

[fille1976]

Ill wait till they come with an update for it and tested it.

[fille1976]

Hi daniel,just got swiss v785,still have no sound in menu with wave race and demo. Crash bandicoot same problem and others. Is there a problem with audio streaming or do i only have this problem?

[danielkraak]

I will look into it asap. I am currently working on a more fundamental update.

I am 99.9% sure that this is a GC Loader issue and updating Swiss will not help, unfortunately.

[fille1976]

Ok,take your time daniel.

Waverace has given me no issues so far with any audio problems in-game, menus, character selection, but I can confirm the problem with Super Monkey Ball that the OP reported occured for me too after competing the first 10 levels. However, music plays on the demo (press start screen) for me.

In addition, Eternal Darkness had some distorted audio when left on the demo loop for several minutes, which corrected itself.

My source for games is redump full iso's. Just copied swiss 827 to my micro sdcard,can't get wave to work with audio in the menu. Have more people issues with it,i see nowhere complaints about streaming audio while i have with some games problem,all redump games,full iso's. Also in this release is a gcloader drive speed emulation,i enabled it,but wave race have still the audio problem,gona try more games now.

[fille1976]

Since i hat contact with daniel i can say my problem is solved,it was the flex cable. Soldered new one in and now i can fully enjoy my gcloader. I tested as many games as possible,no problems found. Thx again to daniel for his fantastic feedback.

[danielkraak]

I was able to reproduce the issue in Wave Race. It seems when an audio stream is started, there is a very small chance that the audio is distorted. The cause is currently under investigation.

[etsuna2345]

Hi, yes thé audio si distorded sometimes When an audio is starter. For ex Extrême G3, crazy taxi, Mario party 7.

This issue has been fixed in update 1.1.2
