Problems with Linux drivers

• USB audio

  • This is a generic class driver, supporting many vendors
  • Texas Instruments PCM2900 – Random record channel swaps
  • Software workaround to determine whether they're swapped

• Via82cxxx chipset

  • OSS 2.4.25 and 2.6.7 – Full duplex never actually plays sound
  • ALSA 2.6.7 – Fragments are two sizes, data not synchronous
  • Software workaround is to keep measuring synchronization
