Bugzilla – Bug 4712
88.2kHz sample rate content plays at half speed, 44.1kHz possibly.

Steven could you verify that this actually works with the current firmware (27)?
I notice 88.2 KHz is not listed on the data sheet. Perhaps I am misremembering that this should work.
According to the documentation, Transporter natively supports sample rates of 44.1kHz, 48kHz & 96kHz. There is no mention of 88.2kHz. Transporter does play a 88.2kHz file, but seems to play it at half speed, possibly at 44.1kHz. Slimserver properly identifies the file as 88.2kHz. I get the same result with with firmware 72 on Squeezebox. I changed the summary and set the severity to enhancement and a target of future. Let me know if that is OK.

I converted the file to WAV with the Microsoft utility wmal2pcm http://www.microsoft.com/windows/windowsmedia/forpros/encoder/utilities.aspx and WAV to FLAC with 1.1.13 using the --lax switch (as FLAC complains about the format of the WAV file. I've seen this also with files created by Adobe Audition). The sample plays as a wma file my SB2 (FW 75, SS 6.5.1 11252), but I suspect it is transcoded to 16bit 44.1kHz rather than 24bit. The WAV file give just noise and the FLAC plays very slowly. Olav Sunde
There has been quite a bit of discussion on the 88.2 sample rate topic on the audiophile forum lately. Is there any progress or work planned for this request?

Sean, could I ask you to address this question about 88.2 support on the Transporter?
I will look at the feasibility of adding down sampling from 88.2kHz to 44.1kHz in the next firmware release. It will also require a small slimserver patch for 88.2kHz WAV.

Keeping support in the loop on this one.
So, Richard, just to clarify: you're planning on downsampling any 88.2 content to 44.1KHz for playback on the Transporter? It's not going to be possible to play content at 88.2 KHz sample rate?
the hardware should be capable of doing native 88.2. this should be considered an interim "fix"
With the 88.2kHz sample rate downloads available from Linn Records, it would be great with native playback on Transporter. Electronic distribution is probably the future of high-res music, so it's a bit sad that Transporter is not capable of playing 88.2kHz files without resampling...
Reassigning Squeezebox firmware bugs to Felix.
Fixed in trunk 17060 / firmware 40. 88.2 is now natively supported and has also been tested with Linn Records' FLACs.
This bug appears to have been fixed in the latest release! If you are still experiencing this problem, feel free to reopen the bug with your new comments and we'll have another look. Make sure to include the version number of the software you are seeing the error with.
