This is a list of known "issues" in the current Rockbox. These are flaws/bugs we know of that are not likely to be fixed within a reasonable time so we list them here and close the bug tracker entries for them. FS#894 - When the complete playlist fits in the mpeg buffer, and the playlist is played multiple times, the tracks are reloaded from disk multiple times instead of loaded only once. FS#2147 - It's a bug in the MAS. It starts bitshifting data on occasion. High load on the MAS makes this behaviour more likely (high recording level, high quality setting, high sample rate). It's impossible to avoid, but there are plans to implement a recording 'framewalker' that checks recorded data and restarts recording when the MAS starts delivering bitshifted data. FS#4937 - A constant rhythmic ticking noise occurs in the right channel. Believed to be related to our slow I2C implementation, and occurs when the battery status and/or realtime clock are updated (the battery is read at up-to 2.5hz and the clock at up-to 1hz). Nothing is going to change with it until someone spends a lot of time analyzing the portalplayer's I2C control registers, or finds a datasheet for the damned thing. FS#5796 - Early encoders such as this one employed a floor of type '0', as opposed to the more efficient/cheaper floor type '1' which has been used in all encoders from libvorbis 1.0 onwards, I believe. The problem appears to be that most DAP decoders can only handle a floor of type '1'. While floor '0' type files like mine are, it turns out, pretty rare, they still conform to the standards, as can be seen in the documention linked below: http://www.xiph.org/vorbis/doc/Vorbis_I_spec.pdf which specifically states that "Floor 0 is not to be considered deprecated..." Files like these require quite a bit of memory to decode, more than what Rockbox has set aside for the purpose. Adding a real malloc for the codecs might help...
