Volvo VSI 不能播放 VBR MP3?

也許有台灣車友遇見跟我相同的問題。

幾週前S60去升級了VSI中文化，發現有些KK BOX下載來的MP3無法播放不了，而且會造成VSI的USB模式當機。解法只有熄火再發動，若是熄火發動間沒有拔掉USB碟，發動後，因為系統會嘗試接續上次撥放的歌曲，所以會再度當機。

本來懷疑是VSI中文化搞壞了，去新莊廠查過後(心疼喔，我的新車就這樣被 熄火/發動, 熄火/發動, 熄火/發動 x N)，發現14年未升級中文的V40也一樣撥不了。技師們說是我的檔案有問題，可能是"另一種MP3格式"。但是同個USB碟同個檔卻可以在非VSI的VOLVO車上正常播放，用WIN XP 或 WIN7電腦可正常播放。 因為是通病，不是中文化搞鬼，所以就離場了。但心裡就是沒放下這件事。

上週末小孩學校給的MP3錄音檔，也不能播放，搞的小毛頭在車上直吵。我也火了。

乖乖GOOGLE後，
1) 另一種MP3格式? 沒找著。轉檔軟體也沒另類MP3讓我選。
2) 有個檔是 0kbps ，懷疑是它把VSI弄垮了! 打算將他從檔案夾移去，再去試。(可是小孩的錄音檔不是0kbps啊..)
3) 找到這個眾歐洲車主們的complaint:

"what is very odd … is the following. The Volvo dealer in Athens tried one of these “bad” MP3 files (that do not play in the V40 High Performance Multimedia system), in an older Volvo car (an XC70) and also at another rental car. And guess what??? It … it plays OK in all other cars !!!!!! So this is another indication, that the V40 does have a software bug. I wonder if Volvo will put their efforts to fix it, or if they will just claim this is not a problem.

The “High performance Multimedia System” specs say that it supports MP3 files with sampling rate up to 320Kbps. Volvo-Italy responded that if we “play” songs with rates 320Kbps … we are “marginally” within the boundaries of the specs.
.... they said that the bit rate is “variable” and that at a couple of instances (during the playback), the bit rate jumps up to 324Kbps…. So they said the file is outside the “standard specs” (320 Kbps max.) and closed the incident. END OF STORY."

所以我查了我那不能撥的檔案夾，剛好全是VBR。不過我還沒查這顆USB碟裡其它可正常撥放的是否都 不是VBR。

還不知道怎麼把VBR改成非VBR。
