      ALSA: dice: unuse second stream for MIDI conformant data channel for TC Electronic models · 84eaaef2
      坂本 貴史 authored
      At present, all of models produced by TC Electronic except for Konnekt Live
      are supported with hard-coded their stream formats. Studio Konnekt 48 is
      sore model to support dual streams for both directions. The second stream
      has no MIDI conformant data channel in its data block. But current
      implementation transfers the second stream with MIDI conformant data
      channel.
      
      This commit fixes this issue.

      ALSA: dice: fix stream format parameters for TC Electronic Studio Konnekt 48 · 1ceb506d
      坂本 貴史 authored
      TC Electronic Studio Konnekt 48 is an application of combination of
      WaveFront Dice II STD and TC Applied Technologies (TCAT) TCD2210 (Dice
      Mini). The latter is on a board with BNC and optical interfaces, thus
      used for signal processing for word clock, S/PDIF and ADAT. This model
      doesn't support TCAT extended application protocol. For such devices,
      ALSA dice driver needs to have hard-coded parameters for stream formats.
      
      This commit fixes stream format parameters for this model. Unfortunately, at
      sampling transmission frequencies over 48.0kHz, I confirmed that current
      ALSA dice driver doesn't drive the device appropriately to generate sounds
      (silence). I guess that this comes from timestamping quirk of Dice-based
      devices, which I reported.

      ALSA: dice: add stream format parameters for TC Electronic Digital Konnekt x32 · d0aa5909
      坂本 貴史 authored
      TC Electronic Digital Konnekt x32 is an application of WaveFront DiceII STD
      and doesn't support TCAT extended application protocol. For such devices,
      ALSA dice driver needs to have hard-coded parameters for stream formats.
      
      This commit adds stream format parameters for this model. Unfortunately, at
      sampling transmission frequencies of 88.2/96.0kHz, I confirmed that current
      ALSA dice driver doesn't drive the device appropriately due to detecting
      packet discontinuities.
      
      $ journalctl
      kernel: snd_dice fw1.0: Detect discontinuity of CIP: 90 80
      
      At the frequencies, the device transfers 16 data blocks per packet and 16
      data channels per data block, as a result one packet includes 1032 bytes
      if it's not NODATA. However, as long as I checked, the device often
      postpone packet transmission and continue with truncated payload than
      metadata in isochronous packet header. Below is a sample of sequence I got.

      I cannot confirm this quirks with Windows driver. ALSA dice driver has a
      cause if assumed differences between these two drivers are ways of
      timestampling to RX packets from the drivers to the device. I've already
      reported timestamping quirk of Dice-based devices and this might bring
      this issue.

      http://mailman.alsa-project.org/pipermail/alsa-devel/2016-May/107715.html
      
      Well, nevertheless, I enable ALSA dice driver to work at the frequencies.
      This may brings inconvenience to users but I expect developers and users
      to fix it.
